B) USING ONLY THE MUTE FUNCTION

To semplify the application, the stand-by pin can

be connected directly to Ground.

During the ON/OFF transitions we recommend to

respect the following conditions:

- At the turn-on the transition mute to play must

be made when the SVR pin is higher than

2.5V

- At the turn-off the TDA7494 must be brought

to mute from the play condition when the SVR

pin is higher than 2.5V.
