Op Amp Voltage Amplifier Circuit. The reason is explained using the voltage follower circuit in figure 1 1 3. The voltage gain is determined by the ratios of r1 and r2 as indicated.

Sine wave input cosine wave output. The schematic representation of an op amp is shown to the left. Non inverting amplifier circuits an op amp can be used as a non inverting dc amplifier with offset compensation by using the connections shown in figure 3 which shows an x10 amplifier.
Sine wave input cosine wave output.
The most common type of op amp is the voltage feedback type and that s what we ll use. Negative feedback is used to reduce the op amp s very high maximum gain to the required level. An op amp circuit forming a voltage amplifier with negative gain set by the ratio of two resistors. The reason is explained using the voltage follower circuit in figure 1 1 3.
