description

The TLV240x family of single-supply operational
amplifiers has the lowest supply current available
today at only 880 nA per channel. Reverse battery
protection guards the amplifier from an overcurrent
condition due to improper battery
installation. For harsh environments, the inputs
can be taken 5 V above the positive supply rail
without damage to the device.
The low supply current is coupled with extremely low input bias currents enabling them to be used with mega-W
resistors making them ideal for portable, long active life, applications. DC accuracy is ensured with a low typical
offset voltage as low as 390 mV, CMRR of 120 dB and minimum open loop gain of 130 V/mV at 2.7 V.
The maximum recommended supply voltage is as high as 16 V and ensured operation down to 2.5 V, with
electrical characteristics specified at 2.7 V, 5 V and 15 V. The 2.5-V operation makes it compatible with Li-Ion
battery-powered systems and many micro-power microcontrollers available today including TI’s MSP430.
All members are available in PDIP and SOIC with the singles in the small SOT-23 package, duals in the MSOP,
and quads in TSSOP.

DESCRIPTION

The TLC77xx family of micropower supply voltage
supervisors provide reset control, primarily in
microcomputer and microprocessor systems.
During power-on, RESET is asserted when VDD
reaches 1 V. After minimum VDD (≥2 V) is
established, the circuit monitors SENSE voltage and
keeps the reset outputs active as long as SENSE
voltage (VI(SENSE)) remains below the threshold
voltage. An internal timer delays return of the output
to the inactive state to ensure proper system reset.
The delay time, td, is determined by an external
capacitor:
td = 2.1 × 104 × CT
Where
CT is in farads
td is in seconds

HEX CLAMPING CIRCUITS

􀀀 Protects Against Latch-Up
􀀀 25-mA Current Sink in Active State
􀀀 Less Than 1-mW Dissipation in Standby
Condition
􀀀 Ideal for Applications in Environments
Where Large Transient Spikes Occur
􀀀 Stable Operation for All Values of

􀀀 No Output Overshoot

description

The TL7726 consists of six identical clamping circuits that monitor an input voltage with respect to a reference
value, REF. For an input voltage (VI) in the range of GND to < REF, the clamping circuits present a very high
impedance to ground, drawing current of less than 10 mA. The clamping circuits are active for VI < GND or
VI > REF when they have a very low impedance and can sink up to 25 mA.
These characteristics make the TL7726 ideal as protection devices for CMOS semiconductor devices in
environments where there are large positive or negative transients to protect analog-to-digital converters in
automotive or industrial systems. The use of clamping circuits provides a safeguard against potential latch-up.
The TL7726C is characterized for operation over the temperature range of 0°C to 70°C. The TL7726I is
characterized for operation over the temperature range of –40°C to 85°C. The TL7726Q is characterized for
operation over the temperature range of –40°C to 125°C.

TL594
PULSE-WIDTH-MODULATION CONTROL CIRCUIT

Features

· Complete PWM Power-Control Circuitry
· Uncommitted Outputs for 200-mA Sink or
Source Current
· Output Control Selects Single-Ended or
Push-Pull Operation
· Internal Circuitry Prohibits Double Pulse at
Either Output
· Variable Dead Time Provides Control Over
Total Range
· Internal Regulator Provides a Stable 5-V
Reference Supply Trimmed to 1%
· Circuit Architecture Allows Easy
Synchronization
· Undervoltage Lockout for Low-VCC Conditions

Description

The TL594 incorporates all the functions required in the construction of a pulse-width-modulation (PWM) control
circuit on a single chip. Designed primarily for power-supply control, this device offers the systems engineer the
flexibility to tailor the power-supply control circuitry to a specific application.
The TL594 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator,
a pulse-steering control flip-flop, a 5-V regulator with a precision of 1%, an undervoltage lockout control circuit,
and output control circuitry.
The error amplifiers have a common-mode voltage range of –0.3 V to VCC – 2 V. The DTC comparator has a
fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating
RT to the reference output and providing a sawtooth input to CT, or it can be used to drive the common circuitry
in synchronous multiple-rail power supplies.
The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Each
device provides for push-pull or single-ended output operation, with selection by means of the output-control
function. The architecture of these devices prohibits the possibility of either output being pulsed twice during
push-pull operation. The undervoltage lockout control circuit locks the outputs off until the internal circuitry is
operational.
The TL594C is characterized for operation from 0°C to 70°C. The TL594I is characterized for operation from
–40°C to 85°C.

Dual Versions of Highly Stable SN54121
and SN74121 One Shots
SN54221 and SN74221 Demonstrate
Electrical and Switching Characteristics
That Are Virtually Identical to the SN54121
and SN74121 One Shots
Pinout Is Identical to the SN54123,
SN74123, SN54LS123, and SN74LS123
Overriding Clear Terminates Output Pulse

description/ordering information

The ’221 and ’LS221 devices are dual
multivibrators with performance characteristics
virtually identical to those of the ’121 devices.
Each multivibrator features a negative-transitiontriggered
input and a positive-transition-triggered
input, either of which can be used as an inhibit
input.

Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input
pulse. Schmitt-trigger input circuitry (TTL hysteresis) for B input allows jitter-free triggering from inputs with
transition at rates as slow as 1 V/s, providing the circuit with excellent noise immunity, typically of 1.2 V. A high
immunity to VCC noise, typically of 1.5 V, also is provided by internal latching circuitry.
Once fired, the outputs are independent of further transitions of the A and B inputs and are a function of the timing
components, or the output pulses can be terminated by the overriding clear. Input pulses can be of any duration
relative to the output pulse. Output pulse length can be varied from 35 ns to the maximum by choosing
appropriate timing components. With Rext = 2 kΩ and Cext = 0, an output pulse typically of 30 ns is achieved
that can be used as a dc-triggered reset signal. Output rise and fall times are TTL compatible and independent
of pulse length. Typical triggering and clearing sequences are shown as a part of the switching characteristics
waveforms.

’147, ’LS147
Encode 10-Line Decimal to 4-Line BCD
Applications Include:
− Keyboard Encoding
− Range Selection

’148, ’LS148
Encode 8 Data Lines to 3-Line Binary
(Octal)
Applications Include:
− n-Bit Encoding
− Code Converters and Generators

description/ordering information

These TTL encoders feature priority decoding of the inputs to ensure that only the highest-order data line is
encoded. The ’147 and ’LS147 devices encode nine data lines to four-line (8-4-2-1) BCD. The implied decimal
zero condition requires no input condition, as zero is encoded when all nine data lines are at a high logic level.
The ’148 and ’LS148 devices encode eight data lines to three-line (4-2-1) binary (octal). Cascading circuitry
(enable input EI and enable output EO) has been provided to allow octal expansion without the need for external
circuitry. For all types, data inputs and outputs are active at the low logic level. All inputs are buffered to represent
one normalized Series 54/74 or 54/74LS load, respectively.

HIGH OUTPUT CURRENT: 70mA
FAST OVERDRIVE RECOVERY

APPLICATIONS

WAFER SCANNING EQUIPMENT
ADC INPUT AMPLIFIER
TEST AND MEASUREMENT FRONT END
HIGH GAIN PRECISION AMPLIFIER

DESCRIPTION
The OPA657 combines a high gain bandwidth, low distortion,
voltage-feedback op amp with a low voltage noise JFET-input
stage to offer a very high dynamic range amplifier for high
precision ADC (Analog-to-Digital Converter) driving or wideband
transimpedance applications. Photodiode applications will see
improved noise and bandwidth using this decompensated,
high gain bandwidth amplifier.
Very low level signals can be significantly amplified in a single
OPA657 gain stage with exceptional bandwidth and accuracy.
Having a high 1.6GHz gain bandwidth product will give
> 10MHz signal bandwidths up to gains of 160V/V (44dB). The
very low input bias current and capacitance will support this
performance even for relatively high source impedances.
Broadband photodetector applications will benefit from the low
voltage noise JFET inputs for the OPA657. The JFET input
contributes virtually no current noise while for broadband
applications, a low voltage noise is also required. The low
4.8nV/ Hz input voltage noise will provide exceptional input
sensitivity for higher bandwidth applications. The example
shown below will give a total equivalent input noise current of
1.8pA/ Hz over a 10MHz bandwidth.

DESCRIPTION/
ORDERING INFORMATION
The LMV321, LMV358, and LMV324/LMV324S are
single, dual, and quad low-voltage (2.7 V to 5.5 V)
operational amplifiers with rail-to-rail output swing.
The LMV324S, which is a variation of the standard
LMV324, includes a power-saving shutdown feature
that reduces supply current to a maximum of 5 μA
per channel when the amplifiers are not needed.
Channels 1 and 2 together are put in shutdown, as
are channels 3 and 4. While in shutdown, the outputs
actively are pulled low.
The LMV321, LMV358, LMV324, and LMV324S are
the most cost-effective solutions for applications
where low-voltage operation, space saving, and low
cost are needed. These amplifiers are designed
specifically for low-voltage (2.7 V to 5 V) operation,
with performance specifications meeting or exceeding
the LM358 and LM324 devices that operate from 5 V
to 30 V. Additional features of the LMV3xx devices
are a common-mode input voltage range that
includes ground, 1-MHz unity-gain bandwidth, and 1-
V/μs slew rate.
The LMV321 is available in the ultra-small DCK (SC-
70) package, which is approximately one-half the size
of the DBV (SOT-23) package. This package saves
space on printed circuit boards and enables the
design of small portable electronic devices. It also
allows the designer to place the device closer to the
signal source to reduce noise pickup and increase
signal integrity.

All inputs are TTL compatible. Each output is a
complete totem-pole drive circuit, with a
Darlington transistor sink and a pseudo-
Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4
enabled by 3,4EN. When an enable input is high, the associated drivers are enabled, and their outputs are active
and in phase with their inputs. When the enable input is low, those drivers are disabled, and their outputs are
off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (or bridge)
reversible drive suitable for solenoid or motor applications.

General Description

The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying
DAC designed to interface directly with the 8080, 8048,
8085, Z80®, and other popular microprocessors. A deposited
silicon-chromium R-2R resistor ladder network divides the
reference current and provides the circuit with excellent
temperature tracking characteristics (0.05% of Full Scale
Range maximum linearity error over temperature). The circuit
uses CMOS current switches and control logic to
achieve low power consumption and low output leakage
current errors. Special circuitry provides TTL logic input voltage
level compatibility.
Double buffering allows these DACs to output a voltage
corresponding to one digital word while holding the next
digital word. This permits the simultaneous updating of any
number of DACs.
The DAC0830 series are the 8-bit members of a family of
microprocessor-compatible DACs (MICRO-DAC™).

2.4-GHz Bluetooth® low energy System-on-Chip

DESCRIPTION

The CC2540 is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applications. It
enables robust BLE master or slave nodes to be built with very low total bill-of-material costs. The CC2540
combines an excellent RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable
flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2540 is suitable
for systems where very low power consumption is required. Very low-power sleep modes are available. Short
transition times between operating modes further enable low power consumption.
The CC2540 comes in two different versions: CC2540F128/F256, with 128 and 256 KB of flash memory,
respectively.
Combined with the Bluetooth low energy protocol stack from Texas Instruments, the CC2540F128/F256 forms
the market’s most flexible and cost-effective single-mode Bluetooth low energy solution.
