Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker.

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 datashheet for 8ohm speakers instead? This circuit can be also powered from 12V DC. BA stereo power amplifier. BA stereo amplifier circuit. You may also like: This design is from BA datasheet.

Are signal and power source ground on dafasheet scheme common,if not can someone tell me which one is signal and wich one i power. Pls what is the value of C11 and C12? A very popular stereo amplifier design. Stereo amplifier based on TDA R3 and R4 sets the datasbeet of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors.


Low distortion and noise. I think the title of the post should be 2x5w stereo power amplifier not 5x2w. C12 is 47uF 25 volts electrolytic capacitor.

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.

This datashet can output 22 watts per channel into 4 ohm loud speakers. The prime objective of bootstrapping is to improve the input impedance. S1 is the standby switch.

Hi C10 and 11 are 2. C4 is the power supply filter capacitor. Additionally, what wattage must the resistors be rated at? Previous post Next post. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input.

Can please tell why 25 volts electrolytic capacitor??? Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit.

Operating voltage is 24V DC. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. C1 bw5417 C5 are bootstrap capacitors. Power output is 32 watts per channel into 4 ohm speakers. TDA stereo amplifier circuit: Potentiometers for controlling the volume is also included in the circuit.

A datasheett amplifier design with a lot of great features like over load protection and thermal shut down. My final question is regarding the speakers. The circuit has good power supply rejection and also there is a built in mute circuitry. Operates from bs5417 DC and requires very few external components.

Suitable for low power car audio applications.

They are earthing or cons? C10 and C11 are 2,2uF. C8 is a filter capacitor. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers. And one more datasheft, what is the value of C10 and C11?
