DESCRIPTION
The DAC7617 is a quad, serial input, 12-bit, voltage
output Digital-to-Analog Converter (DAC) with guar-
anteed 12-bit monotonic performance over the 鈥?0擄C
to +85擄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 is powered from a single +3V supply.
Low power and small size makes the DAC7617 ideal
for automatic test equipment, DAC-per-pin program-
mers, data acquisition systems, and closed-loop servo-
control. The device is available in SO-16 and
SSOP-20 packages and is guaranteed over the
鈥?0擄C to +85擄C temperature range.
