PLAY
Turn ON/OFF Sequences (for optimizing the POP performances)
A) USING MUTE AND STAND-BY FUNCTIONS
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 IL7496L must be brought to mute from the play condition when the SVR pin is higher than 2.5V
