TDA7261 Datasheet, PDF (7/9 Pages) STMicroelectronics – 25W MONO AMPLIFIER WITH MUTE/ST-BY

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 V_pin4 is between +V_S - 2.5V and +V_S
- 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.
