Tygomuro The operating voltage range is from 5 to 15V DC. C9 and C10 are noise filtering capacitors. Purpose of the Zobel network is to reduce oscillations and improve high frequency stability of the amplifier. Can anyone tell how to use single pot volume control for both channels?? Hi Soumen you can use the following circuit a very simple one with sigle control operating both the channels. My requirement is to have separate left and right channels and an extra woofer out.
Is going to be back often to check up on new posts. This makes the IC suitable for low power car audio applications. It can deliver 5W per channel into a 4 ohm loudspeaker at 9V supply. CapacitorsC4 and C8 couple the outputs of the amplifier to the speakers.
Home Questions Tags Users Unanswered. What is the function of capacitor and resistor at pin 4 and 7. Larger caps or a higher impedance speakers would lower the high pass filter rolloff frequency. 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. Your email address will not be published. Try uF, or even 10,uF.
Hi Rahul use a 22k stereo control ganged control. Olin Lathrop k 30 Bx CS 1 2. Sign up or log in Sign up using Google. BA stereo amplifier circuit admin November 3, 11 Comments. I just could not depart your web site prior to suggesting that I really enjoyed the ba info a person provide for your visitors? I have designed a simple stereo amplifier which is attached below, but the bass output was bit poor. Previous post Next post. Hi, what kind of a heatsink does BA need?
C11 and C12 are input DC decoupling capacitors for the left and right channels. Thanks for your response. C1 and C5 are bootstrap capacitors for the left and right channels. Other applications of BA are portable audio players, stereo component systems, television etc. Do you mean that the lower frequencies are not loud enough?
Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Potentiometers R5 and R6 serves as the datsheet control for the left and right channels.
Capacitor C3 is a power supply filter capacitor. You may also like: Related Articles.
