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 (800H) or zero-
scale (000H), 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.

NOTES: (1) LSB means Least Significant Bit; if VREFH equals +10V and VREFL equals –10V, then one LSB equals 4.88mV. (2) All DAC outputs will match within
the specified error band. (3) Ideal output voltage does not take into account zero or full-scale error.
