A power amplifier circuit is the one with minimum output impedance used to drive loads like a speaker which require high power at low impedance. This can be done based on the obtained characteristics of the input values and the output values. Initially there are two type of amplifier circuit diagram is in practical i e.
The easy circuit using a 12v supply.
It helps you to use aa 1 5v battery x2 3v to run a power amplifier. Here we designed a power amplifier circuit using push pull class ab configuration to derive a power of 150w to drive a load of 8 ohms speaker. A power amplifier circuit is the one with minimum output impedance used to drive loads like a speaker which require high power at low impedance. In this circuit one ic 4558 and 4 power transistors are used with some discrete components.
