Description :

• – The module is an MCP3432 A/D converter chip that can provide analog input function for Raspberry Pi and high accuracy analog input for Arduino
• – The MCP3424 is a low noise, high accuracy 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter
• – The device has self-calibration of internal offset and gain per each conversion
• – The device allows the user to select the PGA gain before the analog-to-digital conversion, allowing the device to convert a very weak input signal with high resolution
• – The device has two conversion modes: One-Shot mode and Continuous mode
• – In One-Shot mode, the device performs a single conversion and enters a low current standby mode automatically until it receives another conversion command
• – In Continuous mode, the conversion takes place continuously at the set conversion speed.

– Applications:

•Temperature Sensing with RTD, Thermistor, and Thermocouple
•Bridge Sensing for Pressure, Strain, and Force
•Weigh Scales
•Battery Fuel Gauges
