16-Bit, Quad Voltage Output, Serial Input

DIGITAL-TO-ANALOG CONVERTER

DAC7734

DESCRIPTION

The DAC7734 is a 16-bit, quad voltage output, digital-to-

analog converter (DAC) with ensured 16-bit monotonic

performance over the specified temperature range. It accepts

24-bit serial input data, has double-buffered DAC input logic

(allowing simultaneous update of all DACs), and provides a

serial data output for daisy-chaining multiple DACs.

Programmable asynchronous reset clears all registers to a

mid-scale code of 8000h or to a zero-scale of 0000h. The

DAC7734 can operate from a single +15V supply or from

+15V and –15V, and +5V supplies.

Low power and small size per DAC make the DAC7734

ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closed-loop

servo-control. The DAC7734 is available in a 48-lead

SSOP package and offers ensured specifications over the

–40

°C to +85°C temperature range.
