BA5417 Datasheet PDF

Additionally, what wattage must the resistors be rated at? Can dataheet tell why 25 volts electrolytic capacitor??? Stereo amplifier based on TDA BA is a stereo amplifier IC with a lot of good features datassheet thermal shut down, standby function, soft clipping, wide operating voltage range etc. BA stereo amplifier circuit: Previous post Next post. Your email address will not be published. Low distortion and noise.

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

Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. Leave a Reply Cancel reply Your email address will not be published. This design is from BA datasheet.


Pls what is the datzsheet of C11 and C12? R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors. C8 is dstasheet filter capacitor.

C4 is the power supply filter capacitor. TDA stereo amplifier circuit: BA stereo power amplifier. This amplifier can output 22 datssheet per channel into 4 ohm loud speakers. My final question is regarding the speakers. 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.

A very popular stereo amplifier design. A stereo amplifier design with a lot of great ab5417 like over load protection and thermal shut down.

C10 and C11 are 2,2uF. You may also like: Power output is 32 watts per channel into 4 ohm speakers. They are earthing or cons? The circuit has good power supply rejection and also there is a built in mute circuitry. Setup and working of this stereo power va5417 circuit is somewhat similar to the BA based stereo amplifier circuit published previously. Hi C10 and 11 are 2.

BA Datasheet – Stereo Speaker Amplifier –

Potentiometers for controlling the volume is also included in the circuit. Operating voltage is 24V DC. This circuit can be also powered from 12V DC. 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? Suitable for low power car audio applications.


Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit. The prime objective of bootstrapping is to improve the input impedance. 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.

Operates from 12V DC and requires very few external components. And one more question, what is the value of C10 and C11? C12 is 47uF 25 volts electrolytic capacitor. C1 and C5 are bootstrap capacitors. S1 is the standby switch.
