MCP47FVB28 is a Octal channel 12-bit, voltage output Digital-to-Analog Converter with volatile memory and an I2C compatible serial interface. This device provides four different voltage reference options: device VDD, external VREF (buffered or unbuffered) and internal bandgap. It offers high AC performance, low power consumption and a 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 instruments.
