DESCRIPTION

The DAC7617 is a quad, serial input, 12-bit, voltage

output Digital-to-Analog Converter (DAC) with guar-

anteed 12-bit monotonic performance over the –40

°C

to +85

°C temperature range. An asynchronous reset

clears all registers to either mid-scale (800H) or zero-

scale (000H), selectable via the RESETSEL pin. The

individual DAC inputs are double buffered to allow

for simultaneous update of all DAC outputs. The

device is powered from a single +3V supply.

Low power and small size makes the DAC7617 ideal

for automatic test equipment, DAC-per-pin program-

mers, data acquisition systems, and closed-loop servo-

control. The device is available in SO-16 and

SSOP-20 packages and is guaranteed over the

–40

°C to +85°C temperature range.
