DAC7731

SBAS249B – DECEMBER 2001 – REVISED NOVEMBER 2007

16-Bit, Voltage Output, Serial Input

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

ꢀ LOW POWER: 150mW MAXIMUM

The DAC7731 is a 16-bit Digital-to-Analog Converter (DAC)

which provides 16 bits of monotonic performance over the

specified operating temperature range and offers a +10V

internal reference. Designed for automatic test equipment

and industrial process control applications, the DAC7731

output swing can be configured in a ±10V, ±5V, or +10V

range. The flexibility of the output configuration allows the

DAC7731 to provide both unipolar and bipolar operation by

pin strapping. The DAC7731 includes a high-speed output

amplifier with a maximum settling time of 5µs to ±0.003%

FSR for a 20V full-scale change and only consumes 100mW

(typical) of power.

ꢀ UNIPOLAR OR BIPOLAR OPERATION

ꢀ SETTLING TIME: 5µs to ±0.003% FSR

ꢀ 16-BIT MONOTONICITY, –40°C TO +85°C

ꢀ ±10V, ±5V, OR +10V CONFIGURABLE VOLTAGE

OUTPUT

ꢀ RESET TO ZERO OR MID-SCALE

ꢀ DOUBLE-BUFFERED DATA INPUT

ꢀ DAISY-CHAIN FEATURE FOR MULTIPLE

DAC7731s ON A SINGLE BUS

The DAC7731 features a standard 3-wire, SPI-compatible

serial interface with double buffering to allow asynchronous

updates of the analog output as well as a serial data output

line for daisy-chaining multiple DAC7731s. A user program-

mable reset control forces the DAC output to either min-scale

(0000_h) or mid-scale (8000_h), overriding both the input and

DAC register values. The DAC7731 is available in a

SSOP-24 package and three performance grades specified

to operate from –40°C to +85°C.
