DESCRIPTION

The DAC7724 and DAC7725 are 12-bit quad voltage

output digital-to-analog converters with guaranteed

12-bit monotonic performance over the specified temperature

range. They accept 12-bit parallel input data,

have double-buffered DAC input logic (allowing simultaneous

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

(DAC7724) or to a zero-scale of 000H (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.
