6W+6W STEREO AMPLIFIER WITH MUTE & ST-B

STMicroelectronics 

TDA7499

3 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 generators are switched on and the am-

plifier is in mute mode.

– When Vpin5 lower than = +VS -6V the amplifier is play mode.
