DESCRIPTION
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.
