Pls what is the value of C11 and C12? Previous post Next post. Leave a Reply Cancel reply Your email address will not be published. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously.


R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors. Suitable for low power car audio applications. Operating voltage is 24V DC. Are signal and power source ground on this scheme common,if not can someone tell me which one is signal and wich one i power. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers. The prime objective of bootstrapping is to improve the input impedance.

Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. BA stereo amplifier circuit: BA stereo power amplifier. This amplifier can output 22 watts per channel into 4 ohm loud speakers.

Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker. I think the title of the post should be 2x5w stereo power amplifier not 5x2w.


Potentiometers for controlling the volume is also included in the circuit. C4 is the power supply filter capacitor. C12 is 47uF 25 volts electrolytic capacitor. Can please tell why 25 volts electrolytic capacitor???

They are earthing or cons? C8 is a filter capacitor.

Operates from 12V DC and requires very few external components. Hi C10 and 11 are 2. This design is from BA datasheet. S1 is the standby switch. I understand that when using a circuit that accommodates 4ohm loudspeakers, using 8ohm ab5417 will be safe for the circuit, but is there a way I can optimize the circuit for 8ohm speakers instead?

TDA stereo amplifier circuit: C1 and C5 are bootstrap capacitors.

This circuit can be also powered from 12V DC. Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit.

Low distortion and noise. Stereo amplifier based on TDA A very popular stereo amplifier design. Power output is 32 watts per channel into 4 ohm speakers.
