Overview
The module integrates MCP3432 A/D converter chip. The module can provide analog input function for Raspberry Pi and provide high accuracy analog input for Arduino.
MCP3424 is one of the low noise and high accuracy 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter family members of the MCP342X series.
Characteristic:
Self-calibration internal offset and gain per each conversion.
Users can select the PGA gain before the analog-to-digital converter conversion takes place. This allows the device to convert a very weak input signal with high resolution.
The device have two conversion modes:
(a) One-Shot mode: the device performs a single conversion and enters a low power standby mode automatically until it receives another conversion command.
(b) continuous operation: the conversion takes place continuously at the set conversion speed.
