I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Sign up or ba4506 in Sign up using Google.
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. Try uF, or even 10,uF. Can anyone tell how to use single pot volume control for both channels??
What do you mean by ‘poor’? Potentiometers R5 and R6 serves as the volume control for the left and right channels. Hi, what kind of a heatsink does Datadheet need? C11 and C12 are input DC decoupling capacitors for the left and right channels.
Your email address will not be published. The operating voltage range is from 5 to 15V DC. However, without knowing anything about the chip, it is obvious that really low bass performance will be poor. C9 and C10 are noise filtering capacitors. C1 and C5 are bootstrap capacitors for the left and right channels. It can deliver datasneet per channel into a 4 ohm loudspeaker at 9V supply.
Other applications of BA are portable audio players, stereo component systems, television etc. Olin Lathrop k 30 Home Questions Tags Users Unanswered. Email Required, but never shown.

Previous post Next post. Ranath CS 1 2. Is going to be back often to check up on new posts. Sign up using Facebook. I tried to search for SIP package heatsinks, but nothing good came up. Capacitor C3 is a power supply filter capacitor. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do.

CapacitorsC4 and Datasheeet couple the outputs of the amplifier to the speakers. Post as a guest Name. This makes the IC suitable for low power car audio applications. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency.

BA stereo amplifier circuit admin November 3, 11 Comments. Probably means ‘bass’ output is poor.
It will adtasheet the upper frequencies. What do You mean by “base output is poor”? The problem here is the uF coupling capacitors into a 4 ohm load: Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier.
Hi Rahul use a 22k stereo control ganged control. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. That’s no way to improve the perceived bass response. Do you mean that the lower frequencies are not loud enough?
In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. My requirement is to have separate left and right channels and an extra woofer out.
I don’t have any idea how to do that properly. Leave a Reply Cancel reply Your email address will not be published.
