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. Quick Spec Supply Range: 3-12VDC Magnification: 1.5-1000 times Signal Input Voltage: 100uV – 300mV DC/AC Signal Output Range: ± (Vin-2V) Offset Voltage: 50μV Input Bias Current: 1.0nA (max) Common Mode Rejection Ratio: 100 dB Offset Voltage Drift: 0.6μV / ℃ (maximum) Stability: 2μV / month maximum Dimensions: 32 x 22 x 45 mm (L x W x D) Weight: 4g Board Layout Zero Adjustment Calibration Zero output calibration is done by shorting the input terminals and adjusting the Zero potentiometer until the output is equal to zero Differential Mode Differential Mode is used with bridge type sensors or any sensor with differential output Resources Datasheet Shipping List 1 X AD620 Instrumentation Amp Module
