with guaranteed monotonic behavior. These DACs are
available in both a tiny 6-pin SOT-23 package and an 8-
pin MSOP package. They include a 1.25V reference for
ease of use and flexibility. The reference output is
available on a separate pin, in the 8-pin package version,
and can be used to drive external loads. The operating
supply range is 2.7V to 5.5V.
The input interface is an easy to use three-wire SPI/QSPI
compatible interface. The DAC has a double buffered
digitalkinput.
