TDA7265SA
3 MUTE STAND-BY FUNCTION
The pin 5 (MUTE/STAND-BY) controls the amplifier status by two different thresholds, referred to +V_S.
– When V_pin5 higher than = +V_S -2.5V the amplifier is in Stand-by mode and the final stage generators
are off.
– When V_pin5 between = +V_S -2.5V and V_S -6V the final stage current generators are switched on and
the amplifier is in mute mode.
– When V_pin5 lower than = +V_S -6V the amplifier is play mode.
