DESCRIPTION
The DAC7714 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 (800_H) or zero-
scale (000_H), selectable via the RESETSEL pin. The
device can be powered from a single +15V supply or
from dual +15V and –15V supplies.
Low power and small size makes the DAC7714 ideal
for process control, data acquisition systems, and
closed-loop servo-control. The device is available in a
SO-16 package, and is guaranteed over the –40°C to
+85°C temperature range.
