MCP48FVB22 is a dual channel 12-bit, voltage output Digital-to-Analog Converter with volatile memory and an SPI compatible serial interface. This device provides four different voltage reference options: device VDD, external VREF (buffered or unbuffered) and internal bandgap. It offeres high AC performance, low power consumption and fast settling time, which makes it suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications, and portable instrument.
