The MCP48FEB22-E/UN is a 12-bit buffered voltage output Digital-to-analog Converter (DAC) with nonvolatile memory and an SPI serial interface. The VREF pin, the device VDD or the internal band gap voltage can be selected as the DAC reference voltage. When VDD is selected, VDD is connected internally to the DAC reference circuit. When the VREF pin is used, the user can select the output buffer gain to be 1 or 2. When the gain is 2, the VREF pin voltage should be limited to a maximum of VDD/2. This device has an SPI-compatible serial interface. Write commands are supported up to 20MHz while read commands are supported up to 10MHz.
