The ICM7372, ICM7352 and ICM7332 are 12-Bit, 10-Bit
and 8-Bit
guaranteed
available in 16-pin QSOP package. They include
adjustable output offset 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 for added flexibility.
