description

The TLC7628C, TLC7628E, and TLC7628I 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 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 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.

The TLC7628C operates from a 10.8-V to 15.75-V power supply and is T TL-compatible over this range. 2- or

4-quadrant multiplying makes these devices a sound choice for many microprocessor-controlled gain-setting

and signal-control applications.

The TLC7628C is characterized for operation from 0

°C to 70°C. The TLC7628I is characterized for operation

from – 25

°C to 85°C. The TLC7628E is characterized for operation from –40°C to 85°C.
