OVERVIEW
The ICM7562, ICM7542 and ICM7522 are 12-Bit, 10-Bit
and 8-Bit Voltage Output, Low Power, Dual DACs
respectively, with guaranteed monotonic behavior. These
DACs are available in 08 Lead MSOP package. They have
three Software-Selectable Power-Down Output
Impedances (1 K Ohm, 100 K Ohm and Hi-Z) as additional
safety feature for applications that drive transducers or
valves. 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 Schmitt-
Triggered Inputs for Direct Interfacing to Opto-couplers
easily.
