From the project

Input protection and signal conditioning circuit for 3.3 V ADC systems with fault detection, analog isolation, and buffered output. Designed in KiCad and adaptable to 5 V platforms.

Input Protection and Signal Conditioning Circuit for 3.3 V ADC Systems

This project presents the design and implementation of a robust input protection and signal conditioning circuit intended for low-voltage analog front-end systems operating primarily in a 3.3 V domain. The circuit provides electrical protection, fault detection, controlled signal routing, and buffered output suitable for direct interfacing with analog-to-digital converters (ADCs) in microcontroller or FPGA-based platforms. The design can also be adapted for 5 V systems with minor modifications to supply rails and…
