It will reduce the upper frequencies. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.

5×2 watt BA stereo amplifier . Operates from 9V DC. Low distortion.

The BA has great channel separation, good channel isolation, small pop-up noise, low noise, low thermal va5406 and is available in a 12 pin SIP package. Home Questions Tags Users Unanswered.

I don’t have any idea how to do that properly. Is going to be back often to check up on new posts.

Do you mean that the lower frequencies are not loud enough? Hi Rahul use a 22k stereo control ganged control.

It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Addng a low pass filter won’t improve anything. C1 and C5 are bootstrap capacitors for the left and right channels. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply.

Ranath CS 1 2. Can anyone tell how to use single pot volume control for both channels?? Previous post Next post. So I’m planning to add extra low pass filter circuit to this circuit. You may also like: Hi, what kind of a heatsink does BA need?

The operating voltage range is from 5 to 15V DC. I have designed a simple stereo amplifier which is attached below, but the bass output was dataheet poor. The problem here is the uF coupling capacitors into a 4 ohm load: Sign up or log in Sign up using Google. Thanks for your response. In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is dataaheet the lowest “HiFi” audio frequency.


CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. Potentiometers R5 and R6 serves as the volume control for the left and right channels.

C9 and C10 are noise filtering capacitors. Post as a guest Name. Leave a Reply Cancel reply Your email address will not be published.
