DESCRIPTION

The DAC7615 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

individual DAC inputs are double buffered to allow

for simultaneous update of all DAC outputs. The

device can be powered from a single +5V supply or

from dual +5V and –5V supplies.

Low power and small size makes the DAC7615 ideal

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

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

control. The device is available in 16-pin plastic DIP,

16-lead SOIC, and 20-lead SSOP packages and is

guaranteed over the –40

°C to +85°C temperature range.
