APPLICATIONS

DESCRIPTION

The

DAC7664

is

a

16-bit,

quad

voltage

output

digital-to-analog converter (DAC) with 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 8000h or to a zero-scale

of 0000h. The DAC7664 can operate from a single +5V

supply or from +5V and −5V supplies.

Low power and small size per DAC make the DAC7664

ideal

for

automatic

test

equipment,

DAC-per-pin

programmers, data acquisition systems, and closed-loop

servo control. The DAC7664 is available in an LQFP-64

package and is specified for operation over the −40

°C to

+85

°C temperature range.

This device has ESD-CDM sensitivity and special handling precautions must be taken.
