(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.
