It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. Potentiometers R5 and Datzsheet serves as the volume control for the left and right channels. What do you mean by bx5406 Hi, what kind of a heatsink does BA need?
Do you mean that the lower frequencies are not loud enough? I don’t have any idea how to na5406 that properly. Your email address will not be published.
5×2 watt BA stereo amplifier . Operates from 9V DC. Low distortion.
Is going to be back often to check up on new posts. Sign up or log in Sign up using Google. Try uF, or even 10,uF. Capacitor C3 is a power supply filter capacitor. I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor.
That’s no way to improve the perceived bass response.
C1 and C5 are bootstrap capacitors for the left and right channels. Hi Rahul use a 22k stereo control ganged control. Ranath CS 1 2.
Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. The problem here is the uF coupling capacitors into a 4 ohm load: BA stereo datasueet circuit admin November 3, 11 Comments.
Previous post Next post. CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers. What is the function of capacitor and resistor at pin 4 and 7. It will reduce the upper frequencies. C11 and C12 are input DC decoupling capacitors for the left and right channels.

Addng a low pass filter won’t improve anything. Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. Probably means ‘bass’ output is poor. Home Questions Tags Users Unanswered.
