Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency.
C9 and C10 are noise filtering capacitors. Can ha5406 tell how to use single pot volume control for both channels?? BA stereo amplifier circuit admin November 3, 11 Comments.

I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors? Potentiometers R5 and R6 serves as the volume control for the left and right channels. C1 and C5 are bootstrap capacitors for the left and right channels. Email Required, but never shown. I make it well. Home Questions Tags Users Unanswered. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.
Sign up using Email and Password. I have designed a simple datasheet amplifier which is attached below, but the bass output was bit poor. I don’t have any idea how to do that properly. Post as a guest Datasheeet. Capacitor C3 datashewt a power supply filter capacitor.
Try uF, or even 10,uF. 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.

In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. Leave a Reply Cancel reply Your email address will not be published. Addng a low pass filter won’t improve anything.
That’s no way to improve the perceived bass response. It can deliver ratasheet per channel into a 4 ohm loudspeaker at 9V supply. C11 and C12 are input DC decoupling 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. Hi, what kind of a heatsink does BA need? It will reduce the upper frequencies. Sign up or log in Sign up using Google.
Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do. Ranath CS 1 2.
So I’m planning to add extra low pass filter circuit to this circuit. Previous post Next post. Thanks for your response.
