DESCRIPTION
The DAC7744 is a 16-bit, quad voltage output digital-
to-analog converter with guaranteed 16-bit monotonic
performance over the specified temperature range. It
accepts 16-bit parallel input data, has double-buffered
DAC input logic (allowing simultaneous update of all
DACs), and provides a readback mode of the internal
input registers. Programmable asynchronous reset
clears all registers to a mid-scale code of 8000
H
or to
a zero-scale of 0000
H
. The DAC7744 operates from
either a single +15V supply or from a +15V, 鈥?5V,
and +5V supply.
Low power and small size per DAC make the DAC7744
ideal for automatic test equipment, DAC-per-pin pro-
grammers, data acquisition systems, and closed-loop
servo-control. The DAC7744 is available in a 48-
lead SSOP package, and offers guaranteed specifica-
tions over the 鈥?0擄C to +85擄C temperature range.
