The circuit has good power supply rejection and also there is a built in mute circuitry. TDA stereo amplifier circuit: You may also like: C8 is a filter capacitor.

Previous post Next post. 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? C1 and C5 are bootstrap capacitors. This amplifier can output 22 watts per channel into 4 ohm loud speakers.

Pls what is the value of C11 and C12? Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. And one more question, what is the value of C10 and C11?


Stereo amplifier based on TDA Your email address will not be published. BA stereo amplifier circuit: This design is from BA datasheet. C4 is the power supply filter capacitor. S1 is the standby switch. Potentiometers for controlling the volume is also included datasyeet the circuit.

Can please tell why 25 volts electrolytic capacitor??? Additionally, what wattage must the resistors be rated at? C12 is 47uF 25 volts electrolytic capacitor. Low na5417 and noise. Hi C10 and 11 are 2.

Suitable for low power car audio applications. Networks R1,C3 and R2,C7 are meant for improving the high frequency stability datashete the circuit.

A very popular stereo amplifier design. The prime objective of bootstrapping is to improve the input impedance. They are earthing or cons?

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 power amplifier.

This circuit can be also powered from 12V DC. C10 and C11 are 2,2uF. Simple stereo amplifier circuit that can deliver 5 datashee per channel sound output into a 4 ohm speaker. Operating voltage is 24V DC. BA stereo amplifier circuit. Power output is 32 watts per channel into 4 ohm speakers.


My final question is regarding datasjeet speakers. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously.

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. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers.

I think the title of the post should be 2x5w stereo power amplifier not 5x2w. 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. A stereo amplifier design with a vatasheet of bs5417 features like over load protection and thermal shut down.
