TDA7269A
MUTE STAND-BY FUNCTION
The 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 is lower than +VS -6V the amplifier is play mode.
