2-Channel 16-Bit I2C/Qwiic Analog to Digital Converter

   

I2C-MCP3427

The I2C-MCP3427 is a Qwiic-compatible 2-channel delta-sigma analog to digital converter.  It provides an easy way to get analog sensor data into any project that has a Qwiic-compatible I2C bus, such as a Raspberry Pi.

Features:

  • Dual differential inputs capable of 0-3.3V common mode and +/- 2.048V differential signals
  • Software-adjustable resolution and conversion speed (16 bits @ 15 samples/sec, 14 bits @ 60 samples/sec, 12 bits @ 240 samples/sec)
  • Software-controlled programmable gain amplifier can apply a gain of 1x, 2x, 4x, or 8x to the input signal to avoid external gain amplifiers
  • Built-in 2.048V, 0.05% reference.
  • Plug and play Qwiic connections get your project up and running quickly
  • Solder jumpers for selecting up to 8 different addresses
  • Delta-sigma converter architecture for low-noise measurements
  • Based around the Microchip MCP3427 - consult the datasheet for a full list of features
  • Python control library that works with Raspberry Pi (and compatibles)
