This makes the IC suitable for low power car audio applications. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do. Hi Soumen you can use datashret following circuit a very simple one with sigle control operating both the channels.
Ranath CS 1 2. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply.

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

The problem here is the uF coupling capacitors into a 4 ohm load: Other applications of BA are portable audio players, stereo datadheet systems, television etc. That’s no way to improve the perceived bass response.
Try uF, or even 10,uF. Potentiometers R5 and R6 serves as the volume control for the left and right channels. Capacitor C3 is a power supply filter capacitor.

I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. I don’t have any idea how to do that properly.

Thanks for your response. Hi Rahul use a 22k stereo control ganged control. Hi, what kind of a heatsink does BA need? C11 and C12 are input DC decoupling capacitors for the left and right channels.
CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply.
What do you mean by ‘poor’? Can anyone tell how to use single pot volume control for both channels?? Post as a guest Name.
C9 and C10 are noise filtering capacitors. I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?
