Suitable for low power car audio applications. Operates from 12V DC and requires very few external components.

You may also like: 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 circuit for 8ohm speakers instead?


Hi C10 and 11 are 2. This amplifier can output 22 b5417 per channel into 4 ohm loud speakers. Additionally, what wattage must the resistors be rated at?

C10 and C11 are 2,2uF. The prime objective of bootstrapping is to improve the input impedance. Your email address will not be published. C12 is 47uF 25 volts electrolytic capacitor. Stereo amplifier based on TDA And one more question, what is the value of C10 and C11? 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. ba417

Low catasheet and noise. TDA stereo amplifier circuit: The circuit has good power supply rejection and also there is a built in mute circuitry. Leave a Reply Cancel reply Your email address will not be published.

S1 is the standby switch. R3 and R4 sets the gain of the left and right channels of the amplifier in conjunction with the 39K internal feedback resistors. They are earthing or cons? C8 is a filter capacitor. My final question is regarding the speakers. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input.

I think the title of the post should be 2x5w stereo power amplifier not 5x2w. A stereo amplifier design with daatsheet lot of ha5417 features like over load protection and thermal shut down.

Are signal and power source ground on this scheme common,if not datassheet 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.


Previous post Next post. Can please tell why 25 volts electrolytic capacitor??? BA stereo amplifier circuit: Operating voltage is 24V DC.
