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.

The MCP6022 is a CMOS input opamp, so it has very high input impedance. Even a MΩ is small compared to its input impedance. The other thing to consider is the range of frequencies you want this amplifier to work over. You said the signal is audio, so we'll assume anything below 20 Hz or above 20 kHz is signal you don't care about.

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.

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.
