# ADC Pi Plus (Discontinued)
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. The board is stackable allowing you to use up to four ADC Pi Plus boards on a Raspberry Pi.
## Features
- 8 x 17-bit 0 to 5V Single Ended Inputs
- Control via the Raspberry Pi I2C port
- Stack up to 4 ADC Pi Plus boards on a single Raspberry Pi
- Jumper selectable I2C addresses (0x68 to 0x6F)
- Buffered 5V I2C port
- Based on the MCP3424 from Microchip Technologies Inc
- Single Ended full-scale range of 5.0V
- On-board 2.048V reference voltage (Accuracy ± 0.05%, Drift: 15 ppm/°C)
- On-Board Programmable Gain Amplifier (PGA): Gains of 1, 2, 4 or 8
- Programmable Data Rate Options:
- 3.75 SPS (17 bits)
- 15 SPS (15 bits)
- 60 SPS (13 bits)
- 240 SPS (11 bits)
- One-Shot or Continuous Conversion Options
Arduino, C, Node.js, Windows 10 IOT, Python 2 and Python 3 libraries are available on GitHub.
