description
The TLC7528C, TLC7528E, and TLC7528I are
16

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

with separate on-chip data latches and feature

exceptionally close DAC-to-DAC matching. Data
9 10 11 12 13
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.
