Audio Amplifiers : Speaker / Headphone Amplifier Series |

In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. Can anyone tell how to use single pot datashwet control for both channels??

Do you mean that the lower frequencies are not loud enough? I make it well.

The problem here is the uF coupling capacitors into a 4 ohm load: 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.

Sign up using Email and Password. Previous post Vatasheet post. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. The BA has great channel separation, good channel isolation, small pop-up noise, low noise, low thermal resistance and datasheer available in a 12 pin SIP package.


What do you mean by ‘poor’? Sign up or log in Sign datawheet using Google. Capacitor C3 is a power supply filter capacitor. Probably means ‘bass’ output is poor.

Is going to be back often to check up on new posts. Purpose of the Zobel network is to reduce oscillations and improve datassheet frequency stability of the amplifier. Addng a low pass filter won’t improve anything.

Ranath CS 1 2. I don’t have any idea how to do that properly.

Olin Lathrop k 30 The operating voltage range is from 5 to 15V DC. C9 and C10 are noise filtering capacitors. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Thanks for your response. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do. BA stereo amplifier circuit admin November 3, 11 Comments.

Other applications of BA are portable audio players, stereo component systems, television etc. C11 and C12 are input DC decoupling capacitors for the left and right channels. Potentiometers R5 and R6 serves as the volume control for the left and right channels.


It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Sign up using Facebook. So I’m planning to add extra low pass filter circuit to this circuit. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor.

Post as a guest Name. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.

Email Required, but never shown. 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. I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?

This makes the IC suitable for low power car audio applications. I tried to search for SIP package heatsinks, but nothing good came up.

CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers.
