ADC Pi

The ADC Pi is an 8-channel 17-bit analogue to digital converter designed to work with the Raspberry Pi and other compatible single-board computers. The ADC 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.

This knowledge base section contains articles and tutorials on the ADC Pi, showing how to use the expansion board with a range of input devices.

ADC Sample Rate Comparison

The ADC Pi and ADC Differential Pi from AB Electronics UK use the MCP3424 analogue to digital converter from Microchip. The MCP3424 has programmable bit rates from 12 bits to 18 bits, and the number of samples that can be taken each second depends on the bit rate you have chosen. According to the datasheet for the MCP3424, the data rates are as follows....
