ADC Input 18bit 8ch IIOT Module

Our ADC Input Module is made up of 2x 18bit 4 channel ADC`s allowing 8x analog signals to be sampled with accuracy.

The ADC Chips are MCP3424 which are low noise high accuracy 18-Bit delta-sigma analog-to-digital converter. These devices can convert analog inputs to digital codes with up to 18 bits of resolution.

Some main features of our ADC IIOT Module are:

  • 8x ADC Channels at up to 18bits resolution
  • One-Shot or Continuous Conversion Options
  • Extended Temperature Range: -40°C to +125°C
  • On-Board Programmable Gain Amplifier (PGA) - Gains of 1, 2, 4 or 8
  • Easy to get connected and sampling
  • On-board temperature measurements with the HDC1080 Temp and humidity sensor

System Integration

Can be intergrated into any IIOT system that has a Master controller that supports I2C.

We give example code for Raspberry PI and Arduino hardware.

We also offer system integration and custom code as a service.
