BA Datasheet(PDF) – Rohm

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?

Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. C4 is the power supply filter capacitor. Low distortion and noise. C10 and C11 are 2,2uF. Hi C10 and 11 are 2. This amplifier can output 22 watts per channel into 4 ohm loud speakers. C1 and C5 are bootstrap capacitors. Suitable for low power car audio applications. And one more question, what is the value of C10 and C11?


Simple stereo amplifier circuit that can deliver 5 watt per channel sound output into a 4 ohm speaker. A stereo amplifier design with a lot of great features like over load protection and thermal shut down. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers. Additionally, what wattage must the resistors be rated at? The circuit has good power supply rejection and also there is a built in mute circuitry.

Pls what is the value 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. 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. 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.

Can please tell why 25 volts electrolytic capacitor???

Operating voltage is 24V DC. Operates from 12V DC and requires very few external components. You may also like: BA stereo power amplifier. Your email address will not be published.


BA stereo amplifier circuit: Power output is 32 watts per channel into 4 ohm speakers. Datashet very popular stereo amplifier design. Stereo amplifier based on Datasheef TDA stereo amplifier circuit: Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit.

This design is from BA datasheet. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. BA stereo amplifier circuit. C12 is 47uF 25 volts electrolytic capacitor.

This circuit can be also powered from 12V DC. Leave a Reply Cancel reply Your email address will not be published. My final question is regarding the speakers. S1 is the standby switch.

I think the title of the post should be 2x5w stereo power amplifier not 5x2w. Previous post Next post.

The prime objective of bootstrapping is to improve the input impedance. Potentiometers for controlling the volume is also included in the circuit. C8 is a filter capacitor.
