DESCRIPTION
The DAC7614 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 +5V supply or
from dual +5V and –5V supplies.

Low power and small size makes the DAC7614 ideal
for process control, data acquisition systems, and
closed-loop servo-control. The device is available in
16-pin plastic DIP, 16-lead SOIC, or 20-lead SSOP
packages, and is guaranteed over the –40°C to +85°C
temperature range.
