MUTE STAND-BY TRUTH TABLE
Turn ON/OFF Sequences (for optimising the POP performances)
A) USING MUTE AND STAND-BY FUNCTIONS
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:

PLAY
- At the turn-on the transition mute to play must
- At the turn-off the TDA7494 must be brought
be made when the SVR pin is higher than
2.5V
to mute from the play condition when the SVR
pin is higher than 2.5V.
