What do You mean by “base output is poor”? C9 and C10 are noise filtering capacitors. Your email address will not be published. Home Questions Tags Users Unanswered.
Capacitor C3 is a power supply filter capacitor. Since you didn’t provide a link to the chip datasheet, we don’t know what datasgeet supposed to do. I don’t have any idea how to do that properly. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Can anyone tell how to use single pot volume control for both channels?? Sign up using Email and Password.
Is going to be back often to check up on new posts. Potentiometers Dayasheet and R6 serves as the volume control for the left and right channels. Probably means ‘bass’ output is poor.
Do you mean that the lower frequencies are not loud enough? In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency.
I tried to search for SIP package heatsinks, but nothing good came up. Try uF, or even 10,uF. Sign up using Facebook. CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. My requirement is to have separate left and right channels and an extra woofer out.

That’s no way to improve the perceived bass response. The problem here is the uF coupling capacitors into datasehet 4 ohm load: Ranath CS 1 2. C11 and C12 are input DC decoupling capacitors for the left and right channels.

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 operating voltage range is from 5 to 15V DC.
I make it well. Leave a Reply Cancel reply Your email address will not be published. Hi Rahul use a 22k stereo control ganged control. This makes the IC suitable for low power car audio applications.

C1 and C5 are bootstrap capacitors for the left and right channels. Previous post Next post. Amplifiers based on BA does not require ba55406 output coupling transformer and can be operated from a single supply. Sign up or log in Sign up daatsheet Google. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor. Thanks for your response.
It will reduce the upper frequencies. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier.
What is the function of capacitor and resistor at pin 4 and 7.

Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Other applications of BA are portable audio players, stereo component systems, television etc.
