However, without knowing anything about the chip, it is obvious that really low bass performance will be poor.
Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Hi Rahul use a 22k stereo control ganged control. It will reduce the upper frequencies.
Audio Amplifiers : Speaker / Headphone Amplifier Series |
The operating voltage range is from 5 to 15V DC. Sign up or log in Sign up using Google. What do You mean by “base output is poor”? Potentiometers R5 and R6 serves as the volume control for the left and right daasheet. Try uF, or even 10,uF. Ranath CS 1 2. Other applications of BA are portable audio players, stereo component systems, television etc.

Amplifiers based on BA does not require an output coupling transformer and can be operated from a single datashset. Olin Lathrop k 30 You may also like: I make it well. I tried to search for SIP package heatsinks, but nothing good came up. BA stereo amplifier circuit admin November 3, 11 Comments. Probably means ‘bass’ output is poor.
What is the function of capacitor and resistor at pin 4 and 7. The BA has great channel separation, good channel isolation, small pop-up noise, low noise, low thermal resistance and is eatasheet in a 12 pin SIP package. C11 and C12 are input DC decoupling capacitors for the left and right channels. That’s no way to improve the perceived bass response.
C1 and C5 are bootstrap capacitors for the left and right channels.
My requirement is to have separate left and right channels and an extra woofer out. In this case, the rolloff frequency is 85 Hz, or 2 octaves above what is considered the lowest “HiFi” audio frequency. Can anyone tell how to use single pot volume control for both channels??
Thanks for your response. Your email address will not be published. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. Addng a low pass filter won’t improve anything.
Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. Hi, what kind of a heatsink does BA need? Capacitor C3 is a power supply filter capacitor. Do you mean that the lower frequencies are not loud enough? Previous post Next post.

CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. So I’m planning to add extra low pass filter circuit to this circuit.
It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor.
