Microchip – MCP47FEB01: Digital-to-Analog Converters With Non-Volatile Memory and I2C™


The MCP47FEBxx are single- and dual-channel 8-bit, 10-bit, and 12-bit buffered voltage output Digital-to-
Analog Converters (DAC) with non-volatile memory and an I2C serial interface. The integrated EEPROM enables DAC settings to be recalled at power-up, for added system flexibility. The various shutdown modes significantly reduce the device current consumption for power critical applications. These devices offer customers the ability to utilize the internal band gap for device voltage reference, simplifying development and lowering system cost, or use an external voltage reference source in order to optimize their design.
