DESCRIPTION
The DAC7724 and DAC7725 are 12-bit quad voltage
output digital-to-analog converters with guaranteed
12-bit monotonic performance over the specified tem-
perature range. They accept 12-bit parallel input data,
have double-buffered DAC input logic (allowing simul-
taneous update of all DACs), and provide a readback
mode of the internal input registers. An asynchronous
reset clears all registers to a mid-scale code of 800
H
(DAC7724) or to a zero-scale of 000
H
(DAC7725). The
DAC7724 and DAC7725 can operate from a single
+15V supply, or from +15V and –15V supplies.
Low power and small size per DAC make the DAC7724
and DAC7725 ideal for automatic test equipment,
DAC-per-pin programmers, data acquisition systems,
and closed-loop servo-control. The DAC7724 and
DAC7725 are available in a PLCC-28 or a SO-28
package, and offer guaranteed specifications over the
–40°C to +85°C temperature range.
