OVERVIEW
The ICM7362, ICM7342 and ICM7322 are Dual 12-Bit, 10-
Bit and 8-Bit wide output voltage swing DACs respectively,
ICM7362/7342/7322
DUAL 12/10/8-BIT VOLTAGE-OUTPUT DACS
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. The
operating supply range is 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.
