Non-Inverting Gain Amplifier

The figure below shows a non-inverting gain amplifier using an op amp. It represents a high impedance to the sensor (at the VSEN) and produces a positive gain from VSEN to Vout.



  • High input impedances
  • Low bias current (Complementary Metal Oxide Semiconductor (CMOS) op amps)
  • Positive gain
  • Simplicity


  • Limited input voltage range
  • Input stage distortion
  • Amplifies common mode noise
