OVERVIEW

The ICM7362, ICM7342 and ICM7322 are Dual 12-Bit, 10-

Bit and 8-Bit wide output voltage swing DACs respectively,

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.
