  • Common mode rejection ratio: 100dB
  • Offset voltage drift: 0.6μV/℃ (Max)
  • Dimension: 32x22mm
Features:
  • 1. The AD620 amplification, can amplify microvolt, millivolt, offers higher amplification precision than LM358, the max voltage output range is ± 10V.
  • 2. It uses potentiometer to amplify the input signal, max amplification can be 1000 times, can be adjusted by the potentiometer.
  • 3. It can not only improve the accuracy, but also can avoid the zero drift phenomenon by using the zero potentiometer to adjust the zero.
  • 4. The module adopts 7660A negative voltage chip to output negative voltage(-Vin), can be used to drive other dual power load.
Package Including:
  • 1 x Signal Amplifier Module
