Quad, Serial Input 16-Bit Multiplying Digital-to-Analog Converter
The applied external reference input voltage V
REF
determines the full-scale output current. An internal
feedback resistor (R
) provides temperature tracking
for the full-scale output when combined with an
external I-to-V precision amplifier.
A
high-speed, 3-wire, SPI and microcontroller compat-
ible inputs using serial data in (SDI), clock (CLK), and
a chip-select (CS). In addition, a serial data out pin
(SDO) allows for daisy-chaining when multiple pack-
ages are used. A common level-sensitive load DAC
strobe (LDAC) input allows simultaneous update of all
DAC outputs from previously loaded input registers.
Additionally, an internal power on reset forces the
output voltage to zero at system turn on. An MSB pin
allows system reset assertion (RS) to force all regis-
ters to zero code when MSB = 0, or to half-scale
code when MSB = 1.
