description

The TLC7528C, TLC7528E, and TLC7528I are
dual, 8-bit, digital-to-analog converters (DACs)
designed with separate on-chip data latches and
feature exceptionally close DAC-to-DAC matching.
Data are transferred to either of the two DAC
data latches through a common, 8-bit, input port.
Control input DACA/DACB determines which
DAC is to be loaded. The load cycle of these
devices is similar to the write cycle of a
random-access memory, allowing easy interface
to most popular microprocessor buses and output
ports. Segmenting the high-order bits minimizes
glitches during changes in the most significant
bits, where glitch impulse is typically the
strongest.
These devices operate from a 5V to 15V power supply and dissipates less than 15mW (typical). The 2- or
4-quadrant multiplying makes these devices a sound choice for many microprocessor-controlled gain-setting
and signal-control applications. It can be operated in voltage mode, which produces a voltage output rather than
a current output. Refer to the typical application information in this data sheet.
The TLC7528C is characterized for operation from 0°C to +70°C. The TLC7528I is characterized for operation
from −25°C to +85°C. The TLC7528E is characterized for operation from −40°C to +85°C.
