TDA2052
MUTE/STAND-BY FUNCTION
The pin 3 (MUTE/STAND-BY) controls the ampli-
fier status by three different thresholds, referred
to -VS.
When its voltage is lower than the first threshold
(1V, with a +70mV hysteresis), the amplifier is in
STAND-BY and all the final stage current gener-
ators are off. Only the input MUTE stage is on in
order to prevent pop-on problems.
At Vpin3=1.8V the final stage current generators
are switched on and the amplifier operates in
MUTE.
For Vpin3 =2.7V the amplifier is definitely on
(PLAY condition)
