DESCRIPTION
The DAC7634 is a 16-bit, quad voltage output, digital-
to-analog converter with specified 15-bit monotonic
performance over the specified temperature range. It
accepts 24-bit serial input data, has double-buffered
DAC input logic (allowing simultaneous update of all
DACs), and provides a serial data output for
daisy-chaining multiple DACs. Programmable asyn-
chronous reset clears all registers to a mid-scale
code of 8000_H or to a zero-scale of 0000_H. The
DAC7634 can operate from a single 5-V supply or
from 5-V and –5 V supplies.
Low power and small size per DAC make the
DAC7634 ideal for automatic test equipment,
DAC-per-pin programmers, data acquisition systems,
and closed-loop servo-control. The DAC7634 is avail-
able in a 48-lead SSOP package and offers specifi-
cations over the –40°C to 85°C temperature range.
