The Microchip MCP48FEB01/02 family are 8-bit voltage output Digital-to-Analogue Converters (DACs) that offer high performance with low power consumption and fast settling time. On-board Non-Volatile EEPROM can save DAC settings during power down; four different Voltage Reference options are available. An SPI Interface supports write commands up to 20 MHz and read commands of up to 10 MHz.
