Description

The ADC Differential Pi is an 8 channel 18 bit analogue to digital converter designed to work with the Raspberry Pi. 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.

Features

  • 8 x 18-bit differential inputs 
  • Control via the Raspberry Pi I2C port
  • Stack up to 4 ADC Differential Pi boards on a single Raspberry Pi
  • Jumper selectable I2C addresses
  • Buffered 5V I2C port
  • Based on the MCP3424 from Microchip Technologies Inc
  • Input range of ±2.048V
  • 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 (18 bits)
       - 15 SPS (16 bits)
       - 60 SPS (14 bits)
       - 240 SPS (12 bits)
  • One-Shot or Continuous Conversion Options

Maxiumum Ratings & Specifications

  • Vdd (5V pin on I2C bus): 5.0V
  • All AD inputs and outputs: VSS–0.4V to VDD+0.4 V
  • Current at Input Pins: ±2 mA
