DESCRIPTION
The DAC7615 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
individual DAC inputs are double buffered to allow
GND
for simultaneous update of all DAC outputs. The
device can be powered from a single +5V supply or
from dual +5V and –5V supplies.
Low power and small size makes the DAC7615 ideal
for automatic test equipment, DAC-per-pin program-
mers, data acquisition systems, and closed-loop servo-
control. The device is available in 16-pin plastic DIP,
16-lead SOIC, and 20-lead SSOP packages and is
guaranteed over the –40°C to +85°C temperature range.
