DESCRIPTION

The DAC7644 is a 16-bit, quad voltage output digitalto-

analog converter with guaranteed 15-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 zeroscale

of 0000H. The DAC7644 can operate from a single

+5V supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7644

ideal for automatic test equipment, DAC-per-pin programmers,

data acquisition systems, and closed-loop

servo-control. The DAC7644 is available in a 48-lead

SSOP package and offers guaranteed specifications

over the –40°C to +85°C temperature range.
