The problem here is the uF coupling capacitors into a 4 ohm load: I make it well. What do You datxsheet by “base output is poor”?
Is going to be back often to check up on new posts. Try uF, or even 10,uF.
I tried to search for SIP package heatsinks, but nothing good came up. C1 and C5 are bootstrap capacitors for the left and right channels. Addng a low pass filter won’t improve anything. ba5046
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. You may also like: Sign up using Facebook. C11 and C12 are input DC decoupling capacitors for the left and right channels. BA stereo amplifier circuit admin November 3, 11 Comments.
What do you mean by ‘poor’? C9 and C10 are noise filtering capacitors. Your email address will not be published. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency.

Other applications of BA are portable audio players, stereo component systems, television etc. In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. I just could not depart your web site prior to suggesting that I really enjoyed the standard info a person provide for your visitors?
It satasheet reduce the upper frequencies. The operating voltage range is from 5 to 15V DC. CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. Olin Lathrop k 30 I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor.
I don’t have any idea how to do that properly. That’s no way to improve the perceived bass response. Capacitor C3 datasheeet a power supply filter capacitor. Potentiometers R5 and R6 serves as the volume control 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. Probably means ‘bass’ output is poor. So I’m planning to add extra low pass filter circuit to this circuit.
Home Questions Tags Users Unanswered. Hi, what kind of a heatsink does BA need? 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.

Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.
What is the function of capacitor and resistor at pin 4 and 7. Previous post Next post. Email Required, but never shown. Thanks for your response.

This makes the IC suitable for low power car audio applications. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier.
