DESCRIPTION
The DAC7734 is a 16-bit, quad voltage output, digital-
to-analog converter with guaranteed 16-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 asynchronous
reset clears all registers to a mid-scale code of 8000H or
to a zero-scale of 0000H. The DAC7734 can operate
from a single +15V supply or from +15V and –15V, and
+5V supplies.
Low power and small size per DAC make the DAC7734
ideal for automatic test equipment, DAC-per-pin pro-
grammers, data acquisition systems, and closed-loop
servo-control. The DAC7734 is available in a 48-lead
SSOP package and offers guaranteed specifications
over the –40°C to +85°C temperature range.
