And one more question, what is the value of C10 and C11?

C1 and C5 are bootstrap capacitors. TDA stereo amplifier circuit: Stereo amplifier based on TDA BA stereo amplifier circuit.

Pls what is the value of C11 and C12? BA stereo power amplifier. This circuit can be also powered from 12V DC. Can please tell why 25 volts electrolytic capacitor??? Leave a Reply Cancel reply Your email address will not be published. Your email address will not be published. My final question is regarding the speakers. A very popular stereo amplifier design.

Power output is 32 watts per channel into 4 ohm speakers. They are earthing or cons? Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the datwsheet. This design is from BA datasheet.


C8 is a filter capacitor. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers. 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.

Suitable for low power car audio applications. R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors.

BA Datasheet – Stereo Speaker Amplifier –

The circuit has good power supply rejection and also there is a built in mute circuitry. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. C12 is 47uF 25 volts electrolytic capacitor. Operating voltage is 24V DC. C10 and C11 are 2,2uF.

I think the title of the post should be 2x5w stereo power amplifier not 5x2w. Are signal and power source ground on this scheme common,if not can someone tell me which one is signal b5a417 wich one i power. The prime objective of bootstrapping is to improve the input impedance.


Hi C10 and 11 are 2.

Operates from 12V DC and requires very few external components. You may also like: Low distortion and noise. I understand that when using a circuit that accommodates 4ohm loudspeakers, using 8ohm speakers will be safe for the circuit, but is there a way I can optimize the circuit for 8ohm speakers b5417

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. Previous post Next post. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input.

Potentiometers for controlling the volume is also included in the circuit. BA stereo amplifier circuit: Additionally, what wattage must the resistors be rated at?
