LM158,LM258,LM2904,LM358 Texas Instruments TI pdf datasheet download


Low Power Dual Operational Amplifiers

General Description

The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.

Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which now
can be more easily implemented in single power supply
systems. For example, the LM158 series can be directly
operated off of the standard +5V power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring the additional ±15V
power supplies.
The LM358 and LM2904 are available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package

Unique Characteristics

n In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage.
n The unity gain cross frequency is temperature
n The input bias current is also temperature compensated.

n Two internally compensated op amps
n Eliminates need for dual supplies
n Allows direct sensing near GND and VOUT also goes to
n Compatible with all forms of logic
n Power drain suitable for battery operation


n Available in 8-Bump micro SMD chip sized package,
(See AN-1112)
n Internally frequency compensated for unity gain
n Large dc voltage gain: 100 dB
n Wide bandwidth (unity gain): 1 MHz
(temperature compensated)
n Wide power supply range:
— Single supply: 3V to 32V
— or dual supplies: ±1.5V to ±16V
n Very low supply current drain (500 μA)—essentially
independent of supply voltage
n Low input offset voltage: 2 mV
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
n Large output voltage swing
