DESCRIPTION
The DAC7624 and DAC7625 are 12-bit quad voltage
output digital-to-analog converters with guaranteed 12-
bit monotonic performance over the specified tempera-
ture range. They accept 12-bit parallel input data, have
double-buffered DAC input logic (allowing simulta-
neous 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 800H
(DAC7624) or to a zero-scale of 000H (DAC7625). The
DAC7624 and DAC7625 can operate from a single +5V
supply or from +5V and –5V supplies.
Low power and small size per DAC make the DAC7624
and DAC7625 ideal for automatic test equipment,
DAC-per-pin programmers, data acquisition systems,
and closed-loop servo-control. The DAC7624 and
DAC7625 are available in a 28-pin plastic double-
wide or a 28-lead SOIC package, and offer guaranteed
specifications over the –40°C to +85°C temperature
range.
