Dual 8-bit Voltage-Output DAC with Int/Ext Reference
The ICM7322 is a Dual 8-bit Wide Voltage Swing Output Buffer DAC with 8-bit guaranteed monotonic behaviour. It includes 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. There is 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.
