AC/DC High Precision Small Voltage Signal Amplifier 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. 

Specifications:

  • Input Voltage: 3-12VDC.
  • Magnification: 1.5-1000 times.
  • Signal Input Voltage: 100uV - 300mV DC/AC
  • Signal Output Range: ± (Vin-2V)
  • Negative voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop.
  • 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
