Hi, what kind of a heatsink does BA need? Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Home Questions Fatasheet Users Unanswered. I don’t have any idea how to do that properly. Potentiometers R5 and R6 serves as the volume control for the left and right channels. Olin Lathrop k 30 It will reduce the upper frequencies.
Sign up using Facebook. Do you mean that the lower frequencies are not loud enough? Post as a guest Name. Sign up using Email and Password. Leave a Reply Cancel reply Your email address will not be published. What do You mean by “base output is poor”?
C11 and C12 are input DC decoupling capacitors for the left and right channels. That’s no way to improve the perceived bass response. Hi Rahul use a 22k stereo control ganged control.

In this case, the rolloff datawheet is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. What do you mean by ‘poor’?
My requirement is to have separate left and right channels and an extra woofer out. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply.
I just could datsaheet depart your dataasheet site prior to suggesting that I really enjoyed the standard info a person provide for your visitors? The operating voltage range is from 5 to 15V DC. Can anyone tell how to use single pot volume control for both channels??

BA stereo amplifier circuit admin November 3, 11 Comments. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do. Addng a low pass filter won’t improve anything. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply.
Is going to be back often to check up on new posts. So I’m planning to add extra low pass filter circuit to this circuit. Thanks for your response.
C9 and C10 are noise filtering capacitors. CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. Try uF, or even 10,uF. What is the function of capacitor and resistor at pin 4 and 7.
I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. The BA has great channel separation, good channel isolation, small pop-up noise, low noise, low datashet resistance and is available in a 12 pin SIP package.
Email Required, but never shown. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.

I tried to search for SIP package heatsinks, but nothing good came up. I make it well. Probably means ‘bass’ output is poor. Ranath CS 1 2.
