respectively, with guaranteed monotonic behavior. They
include a 1.25V reference for ease of use and flexibility.
The reference output is available on a separate pin and
can be used to drive the reference input of each DAC.
Alternately, each DAC can be driven by an external
reference. There is a wide operating supply range of 2.7V
to 5.5V.
The input interface is an easy to use three-wire SPI/QSPI
compatible interface. Each DAC can be individually
controlled and has a double buffered digital input. There is
