operate and the power amplifier of channel 2 will be in the
standby mode. In this case only the loudspeaker at
channel 1 can operate and the loudspeaker at channel 2
will be switched off. Setting the SELECT pin to a LOW or
a HIGH voltage results in a reduction of quiescent current
consumption by a factor of approximately 2.
Switching with the SELECT pin during operating is not
plop-free, because the input capacitor of the channel
which is coming out of standby needs to be charged first.
For plop-free channel selecting the device has first to be
set in mute condition with the MODE pin (between 1.5 V
and V
CC
1.5 V), then set the SELECT pin to the new
level, after a delay set the MODE pin to a LOW level.
The delay needed depends on the values of the input
capacitor and the feedback resistors. Time needed is
