Is going to be back often to check up on new posts. Purpose of the Zobel network is to reduce oscillations and improve datassheet frequency stability of the amplifier. Addng a low pass filter won’t improve anything.

Ranath CS 1 2. I don’t have any idea how to do that properly.

Olin Lathrop k 30 The operating voltage range is from 5 to 15V DC. C9 and C10 are noise filtering capacitors. Amplifiers based on BA does not require an output coupling transformer and can be operated from a single supply. Thanks for your response. Since you didn’t provide a link to the chip datasheet, we don’t know what it’s supposed to do. BA stereo amplifier circuit admin November 3, 11 Comments.

Other applications of BA are portable audio players, stereo component systems, television etc. C11 and C12 are input DC decoupling capacitors for the left and right channels. Potentiometers R5 and R6 serves as the volume control for the left and right channels.
