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
asynchronous reset clears all registers to a mid-scale
code of 8000H or to a zero-scale of 0000H. 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
available in a 48-lead SSOP package and offers
specifications over the –40°C to 85°C temperature
range.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
