LM358 Amplifier

The LM358 Amplifier circuit is a versatile audio amplifier employing a low-cost LM358 op-amp. The differential inputs give the amplifier excellent immunity to common-mode signals which are a common cause of amplifier instability.

The LM358 op-amp audio amplifier circuit is the ground point for wiring in a simple design. The ground sensor can show how input is connected to the ground. To the sound source, and not to the amplifier with high currents.

If the power supply of the LM358 amplifier is the signal, one of the inputs of the amplifier is connected to the positive power supply. We can add an NPN common-emitter preamplifier for high gain. The power supply feedback destabilization is greatly reduced.

By the way, the LM358 Op-Amp Audio Amplifier is a fairly poor audio amplifier and you may wish to switch to a better part for reduced distortion. Frankly, for a little bench amplifier, you’ll never notice the distortion.
