DAC7624

DAC7625

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 800

H

(DAC7624) or to a zero-scale of 000

H (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.
