Every amplifier takes in some kind of input signal (a certain current and voltage, which, together multiply to give a certain power level) and produces a bigger output signal (which may have a different current, voltage, or power). One very basic classification we can make is between voltage and power amplifiers.

Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency

Audio Amplifier Circuit. The circuit of the audio amplifier consists of a transistor a device to apply the input signals and a speaker at the output. The transistors are connected based on the necessity. The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion. Higher the gain higher will be the …

R2 & R3 set the DC level of the amplifier's pin 1 input at about half supply voltage. R5 ensures that Vout properly tracks the pin 1 DC level. R5 and R4 set the AC gain. R6 C6 is a Zobel network - Google knows. C3 blocks DC from the speaker. SIMPLE ALTERNATIVE: OR the LM358 circuit from thisSE EE question is very simple and may suit your need.

Operational amplifiers have a basic task. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.
