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.
