Power Amplifier Circuit Diagram. In this circuit one ic 4558 and 4 power transistors are used with some discrete components. 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 circuit is given by emmanuel. Voltage amplifier circuit and power amplifier circuit. The easy circuit using a 12v supply.
An amplifier circuit diagram consists of a signal pick up transducer followed by small signal amplifier s a large signal amplifier and an output transducer.
They form a voltage divider network which supplies the base of the transistor with a voltage 0 7v higher than the negative maximum amplitude swing of the input signal. It helps you to use aa 1 5v battery x2 3v to run a power amplifier. Use 20v to 60v for operating this circuit. 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.
