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. Can please tell why 25 volts electrolytic capacitor???

A stereo amplifier design with a lot of great features like over load protection and thermal shut down. The prime objective of bootstrapping is to improve the input impedance.

Potentiometers for controlling the volume is also included in the circuit. I understand that when using a circuit that accommodates 4ohm loudspeakers, using 8ohm speakers will be safe for the circuit, bx5417 is there a way I can optimize the circuit for 8ohm speakers instead?

BA is a stereo amplifier IC with a lot of good features like thermal shut down, standby function, soft clipping, wide operating voltage range etc. A very popular stereo amplifier design. Suitable for low power car audio applications. Low distortion and noise. C12 is 47uF 25 volts electrolytic capacitor. Your email address will not be published. Power output is 32 watts per dztasheet into 4 ohm speakers.

Datasheer and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input.


Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit.

Previous post Next post. C4 is the power supply filter capacitor. Hi C10 and 11 are 2. This amplifier can output 22 watts per channel into 4 ohm loud speakers.

BA stereo amplifier circuit: C10 and C11 are 2,2uF. They are earthing or cons?

And one more question, what is the value of C10 and C11? C2 and C6 couples the amplifiers left and right power outputs to datawheet corresponding loud speakers.

BA stereo amplifier circuit. C1 and C5 are bootstrap capacitors. Additionally, what wattage must the resistors be rated at? Operates from 12V DC and requires very few external components.
