AD620 Microvolt Amplifier Module, Adjustable Gain Instrumentation Amplifier Board

Struggling with weak sensor signals that your microcontroller simply can't read accurately? The AD620 Microvolt Amplifier Module solves exactly that — delivering clean, stable, and precisely amplified signals from even the faintest analog sources, right out of the box.

Built around the industry-trusted AD620 instrumentation amplifier IC, this compact module accurately amplifies signals in the 100 µV to 300 mV range with a gain adjustable from 1.5X all the way up to 10,000X via an onboard potentiometer — no external resistors needed. With a high Common Mode Rejection Ratio (CMRR) of 100 dB and an ultra-low offset drift of just 0.6 µV/°C, it maintains rock-solid measurement accuracy even in thermally variable lab or field environments. The wide power supply range of 3V to 12V DC makes it plug-and-play compatible with Arduino, ESP32, Raspberry Pi, and virtually any embedded or lab setup you're already running.

This module is purpose-built for electronics engineers, students, and makers working on precision measurement projects — think Wheatstone bridge sensors, ECG/biomedical signal acquisition, strain gauges, thermocouple amplification, or IoT sensor conditioning. If your project demands signal integrity at the microvolt level, this board delivers without compromise.
