OVERVIEW
The ICM7373, ICM7353 and ICM7333 are Dual 12-Bit, 10-
Bit and 8-Bit Rail-to-Rail voltage output DACs respectively,
with guaranteed monotonic behavior. These DACs are
available in 16 Lead QSOP package. They include
adjustable output gain for ease of use and flexibility. The
reference output is available on a separate pin 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
and Microwire compatible interface. The DAC has a
double buffered digital input. And there is a serial data
output port to allow daisy-chaining applications.
