ICmic ICM7363
The ICM7363, ICM7343 and ICM7323 are Quad 12-Bit, 10-Bit and 8-Bit wide output voltage swing DACs BLOCK DIAGRAM 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.FEATURES

APPLICATIONS
Battery-PoweredAPPLICATIONS
Industrial Process Control Digital Gain and Offset Adjustment OVERVIEW Alternately, each DAC can be driven by an external reference. There is a wide operating supply range of 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. There is a serial data output to allow for daisy-chaining applications.
