In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. That’s no way to datashewt the perceived bass response. What is the function of capacitor and resistor at pin 4 and 7. Hi, what kind of a heatsink does BA need?

Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.

I tried to search for SIP package datazheet, but nothing good came up. Email Required, but never shown. Probably means ‘bass’ output is poor.

Post as a guest Name. The problem here is the uF coupling capacitors into a 4 ohm load: I dataaheet could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors? The BA has great channel separation, good channel isolation, small datasheer noise, low noise, low thermal resistance and is available in a 12 pin SIP package.

Addng a low pass filter won’t improve anything. What do You mean by “base output is poor”? Thanks for your response.

Other applications of BA are portable ga5406 players, stereo component systems, television etc. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. 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.

Try uF, or even 10,uF. You may also like: Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Your email address will not be published.

This bz5406 the IC suitable for low power car audio applications. C9 and C10 are noise filtering capacitors. The operating voltage range is from 5 to 15V DC. Amplifiers based on BA does not require an fatasheet coupling transformer and can be operated from a single supply. What do you mean by ‘poor’? Sign up or log in Sign up using Google.

It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Can anyone tell how to use single pot volume control for both channels?? Olin Lathrop k 30 Is going to be back often to check dahasheet on new posts. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency.
