I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors? Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.

What is the function of capacitor and resistor at pin 4 and 7. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Capacitor C3 is a power bz5406 filter capacitor. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier.

Thanks for your response.

Can anyone tell how to use single pot volume control for both channels?? Hi Rahul use a 22k stereo control ganged control.

BA stereo amplifier circuit admin November 3, 11 Comments. Your email address will not be published. The operating voltage range is from 5 to 15V DC. Previous post Next post. Do you mean that the lower frequencies are not loud enough? Sign up using Facebook. Home Questions Tags Users Unanswered. So I’m planning to add extra low pass filter circuit to this circuit.


This makes the IC suitable for low power car audio applications. C11 and C12 are input DC decoupling capacitors for the left and right channels. It can deliver datasjeet per channel into a 4 ohm loudspeaker at 9V supply. Email Required, but never shown.

What do You mean by “base output is poor”? Post as a guest Name. Other applications of BA are portable audio players, stereo component systems, television etc. Leave a Reply Cancel reply Your email address will not be published. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Larger caps or a higher impedance speakers would datashet the high pass filter rolloff frequency. C9 and C10 are noise filtering capacitors.

BA , Tube BA; Röhre BA ID, IC – Integrated

Potentiometers R5 and R6 serves as the volume control for the left and right channels. I make it well. That’s no way to improve the perceived bass response.

The BA has great channel separation, good channel isolation, small pop-up datashee, low noise, low thermal resistance and is available in a 12 pin SIP package.

In this case, the rolloff frequency is datashheet Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency.

Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels.

Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Olin Lathrop k 30
