BA is a stereo amplifier IC with a lot ha5417 good features like thermal shut down, standby function, soft clipping, wide operating voltage range etc.

Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers.

C1 and C5 are bootstrap capacitors. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. The prime objective of bootstrapping is to improve the input b5a417.

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


C4 is the power supply filter capacitor. S1 is the standby switch. C8 is a filter capacitor. R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors.

BA stereo amplifier circuit: Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker. Operates from 12V DC and requires very datashret external components. Suitable for low power car audio applications. TDA stereo amplifier circuit: A very popular stereo amplifier design.

This amplifier can output 22 watts per channel into 4 ohm loud speakers. This circuit can be also powered from 12V DC. Low distortion and noise. Power output is 32 watts per channel into 4 ohm speakers. Stereo amplifier based on TDA A stereo amplifier design with a lot of great features like over load protection and thermal shut down. Operating voltage is 24V DC. Potentiometers for controlling the volume is also included in the circuit.

The circuit has good power supply rejection and also there is a built in mute circuitry. 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. Hi C10 and 11 are 2. C12 is 47uF 25 volts electrolytic capacitor. Additionally, what wattage must the resistors be rated at?


My final question is regarding the speakers. 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?

BA stereo amplifier circuit. Previous post Next post. You may also like: Can please tell why 25 volts electrolytic capacitor???

Pls what is the value of C11 and C12? C10 and C11 are 2,2uF.

This design is from BA datasheet. And one more question, what is the value of C10 and C11? I think the title of the post should be 2x5w stereo power amplifier not 5x2w. Leave a Reply Cancel reply Your email address will not be published.
