description

The TLC7528C, TLC7528E, and TLC7528I are

dual, 8-bit, digital-to-analog converters designed

with separate on-chip data latches and feature

exceptionally close DAC-to-DAC matching. Data

is 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 5-V to 15-V power supply and dissipates less than 15 mW (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.
