Non-Inverting Gain Amplifier

Last modified by Microchip on 2023/11/09 09:03

Figure 1 shows a non-inverting gain amplifier using an op amp. It represents a high impedance to the sensor (at the V_SEN) and produces a positive gain from V_SEN to Vout.

Advantages

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

Disadvantages

Limited input voltage range
Input stage distortion
Amplifies common mode noise

Sensor examples

Thermocouple
Thermopile
Piezo-electric film
