USING ONLY THE MUTE FUNCTION
To semplify the application, the stand-by pin can be connected directly to Ground. During the ON/OFF transi-
tions is recommended to respect the following conditions:
– At the turn-on the transition mute to mute - play must be made when the SVR pin is higher than 2.5V
– At the turn-off the SH7496 must be brought to mute from the play condition when the SVR pin is
higher than 2.5V.
