Schematic PIC Data Logger with Delta-Sigma Converter

The aim of the project is to build a lab-grade data logger with PIC18F45K20 microcontroller and a 20-bit delta-sigma converter. It’s named as G5 Data Logger.

This new data converter technology using delta-sigma simplifies the design of high resolution data recording device. One of the interesting chip is Linear Technology LTC2400, 24-bit ADC. Another chip of interest is LTC2420, 20-bit ADC.
