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.
