Mute standby function
TDA7265B
Pin 5 (MUTE/St-By) controls the amplifier status using two different thresholds with
reference to +VS :
● when Vpin5 is greater than or equal to +VS - 2.5 V, the amplifier is in standby mode and
the final stage generators are off
● when Vpin5 is between +VS - 2.5V and +VS 6 V, the final stage current generators are
switched on and the amplifier is in mute mode
● when Vpin5 is less than +VS - 6 V, the amplifier is in play mode.
