SINGLE 12/10/8-BIT VOLTAGE-OUTPUT DACS
with guaranteed monotonic behavior. These DACs are available in both a tiny 6-pin SOT-23 package and an 8pin 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.
