16-Bit, Voltage Output, Serial Input
DIGITAL-TO-ANALOG CONVERTER
DESCRIPTION
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’s
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 5
μ
s to
±
0.003%
FSR for a 20V full-scale change and only consumes 100mW
(typical) of power.
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 DAC7731’s. 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.
