(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 GMA7496L must be brought to mute from the play condition when the SVR pin
is higher than 2.5V.
