MCP48FEB22 is a dual channel, 12-bit, voltage output Digital-to-Analog Converter with EEPROM 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. The device has integrated EEPROM to save DAC settings at power down. It is suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications, and portable instrument.
