Precision Instrumentation Amplifier — AD620 Module
The AD620 Signal Amplifier Module is a low-noise instrumentation amplifier designed to amplify tiny microvolt and millivolt signals — the kind produced by strain gauges, thermocouples, load cells, biomedical sensors (ECG/EMG), and other precision measurement devices. Unlike audio amplifiers, this module is built for DC and low-frequency signal conditioning.
This is not an audio amplifier. The AD620 is a precision instrumentation amplifier for sensor signal conditioning. Looking for audio? See our audio amplifier modules.
Why choose it
- High gain accuracy: Gain set by a single external resistor
- Low noise: 9 nV/√Hz — ideal for microvolt-level signals
- High CMRR: Excellent common-mode rejection for noisy environments
- Low power: Only 1.3 mA max supply current
