Op amps always operate with some amount of external feedback where some of the output signal is fed back into the input. If we start looking at op amp circuits, we can see how this is being done with feedback resistor RF. To the right is your typical inverting op amp circuit, the gain of which is determined by Rf / Ri.

The op-amp output is connected to the center of diode-resistor biasing circuitry, and this signal manipulate the biasing point. At idle condition, when there is no signal in the input, the output should be bet at Vcc/2.

Amplifiers are used almost in all the audio related applications. Power amplifier is the part of sound electronics. It is designed to maximize the magnitude of the power of given input signal. In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load.

When an opamp is operated in its linear mode (which is most of the time for audio and most other amplification circuits), the negative feedback circuit will cause a voltage to appear on the inverting input (-in) that is ( almost) exactly equal to that present on the non-inverting input (+in).

An audio amplifier chip, such as an LM386, is capable of driving high currents into low-resistance loads, such as a loudspeaker. Most opamps can supply only a few tens of milliamps. shteii01 Joined Feb 19, 2010 4,644 May 7, 2017 #3 To start with. Audio is defined as frequencies from 20 Hz to 20 kHz. So.
