B) USING ONLY THE MUTE FUNCTION

To simplify the application, the stand-by pin can

be connected directly to Ground.

During the ON/OFF transitions is recommend to

respect the following conditions.

- At the turn-on, the transition mute - play must be

made when the SVR pin is higher than 2.5V

- At the turn-off, the TDA7496L must be brought

to mute from the play condition when the SVR pin

is higher than 2.5V.
