DAC7641

DESCRIPTION

The DAC7641 is a 16-bit, voltage output digital-to-

analog converter (DAC) with guaranteed 15-bit mono-

tonic performance over the specified temperature range.

It accepts 16-bit parallel input data, has double-buffered

DAC input logic (allowing asynchronous update), and

provides a readback mode of the internal input registers.

Programmable asynchronous reset clears all registers to

a mid-scale code of 8000

H or to a zero-scale of 0000H.

The DAC7641 can operate from a single +5V supply or

from +5V and –5V supplies.

Low power and small size per DAC make the DAC7641

ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closed-

loop servo-control. The DAC7641 is available in a

TQFP-32 package, and offers guaranteed specifica-

tions over the –40

°C to +85°C temperature range.
