# ADC Differential Pi Support

Support Forum for the ADC Differential Pi

The ADC Differential Pi is an 8-channel, 18-bit analogue to digital converter designed to work with the Raspberry Pi and other compatible single-board computers. The ADC Differential Pi 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.
