Microchip Technology MCP47FVB12A3T-E/ST

Description
The MCP47FVBXX are single- and dual-channel 8-bit, 10-bit, and 12-bit buffered voltage output Digital-to-Analog Converters (DACs) with volatile memory and an I²C serial interface. The VREF pin, the device VDD, or the internal band gap voltage can be selected as the DAC's reference voltage. When VDD is selected, VDD is connected internally to the DAC reference circuit. When the VREF pin is used, the user can select the output buffer's gain to be 1 or 2. When the gain is 2, the VREF pin voltage should be limited to a maximum of VDD/2.
These devices have a two-wire I²C-compatible serial interface for Standard (100 kHz), Fast (400 kHz), or High-Speed (1.7 MHz and 3.4 MHz) modes.
