Additionally, what wattage must the resistors be rated at? 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. Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker.

C8 is a filter capacitor. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud 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? The circuit datasheeet good power supply rejection and also there is a built in mute datashee.


Low distortion and noise. You may also like: Hi C10 and 11 are 2. Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit. C10 and C11 are 2,2uF.

S1 is the standby switch. Datashret is a method in which a portion of the amplifiers is taken and applied to the input. 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. The prime objective of bootstrapping datasbeet to improve the input impedance.

A stereo amplifier design with a lot of great features like over load protection and thermal shut down. BA stereo amplifier circuit.

This circuit can be also powered from 12V DC. Operates from 12V DC and requires very few external components.


Operating voltage is 24V DC. A very popular stereo amplifier design. And one more question, what is the value of C10 and C11?

R3 and R4 sets the gain of the left and darasheet channels of the amplifier in conjunction with the 39K internal feedback resistors. This amplifier can output 22 watts per channel into 4 ohm loud speakers. C1 and C5 are bootstrap capacitors. I think the title of the post should be 2x5w stereo power amplifier not 5x2w.

C4 is the power supply filter capacitor. C12 is 47uF 25 volts electrolytic capacitor. Pls what is the value of C11 and C12?

Power output is 32 watts per channel into 4 ohm speakers. Leave a Reply Cancel reply Datsheet email address will not be published. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. Potentiometers for controlling the volume is also included in the circuit.
