DESCRIPTION
The DAC7616 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
device is powered from a single +3V supply.
Low power and small size makes the DAC7616 ideal
GND
for process control, data acquisition systems, and
closed-loop servo-control. The device is available in
SO-16 or SSOP-20 packages, and is guaranteed over
the –40°C to +85°C temperature range.
