Digital Operational Amplifier
This project demonstrates how to build a digital operational amplifier using an ESP32 microcontroller. By leveraging the ESP32's analog-to-digital converters and digital-to-analog output capabilities, this guide shows how to implement op-amp functions like amplification, filtering, and signal conditioning entirely in software.
The guide includes a complete wiring diagram, parts list, and firmware code to get started. Readers will learn how to configure the ESP32's ADC inputs and DAC outputs, implement real-time signal processing algorithms, and understand the trade-offs between analog and digital implementations of classic op-amp circuits.
