... The mute circuit is also activated during turn- on/turn-off operations when the voltage at stand- by pin is lower than about 2 volt Figure 18: Soft Muting TURN-ON The TDA7256 is fully popless at turn-on thanks to a delay circuit which keeps the output low during the capacitors charge transient. The delay-time is given by the following formula: T ...
