DESCRIPTION

The DAC7744 is a 16-bit, quad voltage output digitalto-

analog converter with guaranteed 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 DAC7744 operates from

either a single +15V supply or from a +15V, –15V,

and +5V supply.

Low power and small size per DAC make the DAC7744

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

data acquisition systems, and closed-loop

servo-control. The DAC7744 is available in a 48-

lead SSOP package, and offers guaranteed specifications

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