DIGITAL-TO-ANALOG CONVERTER

DAC7641
DESCRIPTION
The DAC7641 is a 16-bit, voltage output digital-to-
analog converter (DAC) with guaranteed 15-bit mono-
tonic performance over the specified temperature range.
It accepts 16-bit parallel input data, has double-buffered
DAC input logic (allowing asynchronous update), and
provides a readback mode of the internal input registers.
Programmable asynchronous reset clears all registers to
a mid-scale code of 8000
H
or to a zero-scale of 0000
H
.
The DAC7641 can operate from a single +5V supply or
from +5V and –5V supplies.
Low power and small size per DAC make the DAC7641
ideal for automatic test equipment, DAC-per-pin
programmers, data acquisition systems, and closed-
loop servo-control. The DAC7641 is available in a
TQFP-32 package, and offers guaranteed specifica-
tions over the –40°C to +85°C temperature range.
