I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?
CapacitorsC4 dataseet C8 couple the outputs of the amplifier to the speakers. Home Questions Tags Users Unanswered. I tried to search for SIP package heatsinks, but nothing good came up. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply.
C11 and C12 are input DC decoupling capacitors for the left datsaheet right channels.
5×2 watt BA stereo amplifier . Operates from 9V DC. Low distortion.
It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. I don’t have any idea how to do that dztasheet. The operating voltage range is from 5 to 15V DC. C9 and C10 are noise filtering capacitors.

What is the function of capacitor and resistor at pin 4 and 7. That’s no way to improve the perceived bass response. What do You mean by “base output is poor”? Probably means ‘bass’ output is poor. Sign up using Facebook.
BA , Tube BA; Röhre BA ID, IC – Integrated
It will reduce the upper frequencies. I make it well. Hi, what kind of a heatsink does BA need? Leave a Reply Cancel reply Your email address will not be published.
My datashest is to have separate left and right channels and an extra woofer out. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Hi Rahul use a 22k stereo control ganged control.
BA5406 Datasheet PDF
datahseet Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. Email Required, but never shown. Olin Lathrop k 30 Sign up using Email and Password. The problem here is the uF coupling capacitors into a 4 ohm load: Capacitor C3 is a power supply filter capacitor.
Hi Soumen you can use ba540 following circuit a very simple one with sigle control operating both the channels. You may also like: Other applications of BA are portable audio players, stereo component systems, television etc.
What do you mean by ‘poor’? In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest datasheef audio frequency. Thanks for your response. Addng a low pass filter won’t improve anything. C1 and C5 are bootstrap capacitors for the left and right channels.
Do you mean that the lower frequencies are not loud enough? Can anyone tell how to use single pot volume control for both channels?? BA stereo amplifier circuit admin November 3, datashdet Comments.
Your email address will not be published. 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. This makes the IC suitable for low power car audio applications. Previous post Next post. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.
