DESCRIPTION
The DAC7616 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
device is powered from a single +3V supply.
Low power and small size makes the DAC7616 ideal

SO-16 or SSOP-20 packages, and is guaranteed over
the 鈥?0擄C to +85擄C temperature range.
