Description

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 offers 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 instruments. For different resolutions and number of output channels, please check out our other parts in the MCP48FVBxx family.
