ADC Pi Plus

The ADC Pi Plus is an 8 channel 17 bit analogue to digital converter designed to work with the Raspberry Pi. The ADC Pi Plus is based on two Microchip MCP3424 A/D converters each containing 4 analogue inputs. The MCP3424 is a delta-sigma A/D converter with low noise differential inputs.
