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.
TDA7261
- 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.
