STMicroelectronics 

MUTE STAND-BY FUNCTION

The pin 4 (MUTE/STAND-BY) controls the ampli-

fier status by two different theresholds, referred to

+VS.

- When Vpin4 higher than = +VS - 2.5V the

amplifier is in Stand-by mode and the final

stage generators are off.

- When Vpin4 is between +VS - 2.5V and +VS

- 6V the final stage current generators are

switched on and the amplifier is in mute

mode.

- When Vpin4 is lower than +VS - 6V the am-

plifier is play mode.
