The MCP331x1D-10 are fully-differential 16, 14, and 12-bit, 1 Msps single-channel ADC family devices, featuring low power consumption and high performance, using a successive approximation register (SAR) architecture. The device operates with a 2.5V to 5.1V external reference (VREF), which supports a wide range of input full-scale range from -VREF to +VREF. The reference voltage setting is independent of the analog supply voltage (AVDD) and is higher than AVDD. The conversion output is available through an easy-to-use simple SPI- compatible 3-wire interface.
