TDA7265SA(*) In mute condition the current drawn from Pin 5 must be ≤650µA

otherwise specified)
TDA7265SA MUTE STAND-BY FUNCTIONThe pin 5 (MUTE/STAND-BY) controls the amplifier status by two different thresholds, referred to +VS. When Vpin5 higher than = +VS -2.5V the amplifier is in Stand-by mode and the final stage generators
are off. When Vpin5 between = +VS -2.5V and VS -6V the final stage current generators are switched on and
the amplifier is in mute mode. When Vpin5 lower than = +VS -6V the amplifier is play mode.
