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 match-

ing. 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.
