AD620 Instrumentation Amp Module

This device uses an AD620 as an amplifier that is capable of amplifying small voltage signal (e.g. µV) AC or DC. By adjusting the on-board potentiometer, the magnification can be adjusted to go as high as up to 1000 times. This module has a low voltage offset, great linearity, and also, an adjustable zero potentiometer to improve its accuracy.
