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.

Hi C10 and 11 are 2. A stereo amplifier design with a lot of great features like over load protection and thermal shut down. BA stereo amplifier circuit. C8 is a filter capacitor. Low distortion and noise. Previous post Next post. I think the title of the post should be 2x5w stereo power amplifier not 5x2w.

Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit. Potentiometers for controlling the volume is also included in the circuit. Your email address will not be published. Pls what is the value of C11 and C12?


C1 and C5 are bootstrap capacitors. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers.

Power output is 32 watts per channel into 4 ohm speakers. C4 is the power supply filter capacitor. Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker.

R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors. Additionally, what wattage must the resistors be rated at? Ratasheet one more question, what is the value of C10 and C11?

The circuit datasheeet good power supply rejection and also there is a built in mute circuitry. C12 is 47uF 25 volts electrolytic capacitor. A very popular stereo amplifier design.

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 instead? This circuit can be also powered from 12V DC.


You may also like: BA stereo amplifier circuit: Stereo amplifier based on TDA Operates from 12V DC and requires very few external components. C10 and C11 are 2,2uF.

Operating voltage is 24V DC. This amplifier can output 22 watts per channel into 4 ohm loud speakers.

Can please tell why 25 volts electrolytic capacitor??? This design is from BA datasheet. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input.

They are earthing or cons? 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. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously.

Suitable for low power car audio applications.

TDA stereo amplifier circuit: My final question is regarding the speakers. The prime objective of bootstrapping is to improve the input impedance.
