DEVICE DESCRIPTION
The AD5764R has a nominal output voltage span of ±10 V
derived from an internal 10 ppm/°C reference voltage of +5 V.
The part also includes a 3-wire serial interface that is compatible
with SPI, QSPI™, MICROWIRE™, and DSP interface standards.
Data is written to the AD5764R in a 24-bit word format, and a
data output pin (SDO) is also offered for daisy-chaining or
readback.

The DAC outputs are updated upon reception of new data into
the DAC registers. All outputs can be simultaneously updated
by taking the LDAC input low.
