The DAC7715 is a quad, serial input, 12-bit, voltage
output Digital-to-Analog Converter (DAC) with
guaranteed 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 individual DAC inputs are double buffered to
allow for simultaneous update of all DAC outputs.
The device can be powered from a single +15V supply
or from dual +15V and –15V supplies.
Low power and small size makes the DAC7715 ideal
for automatic test equipment, DAC-per-pin program-
mers, 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 tempera-
ture range.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
