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.
