SELECT pin
If the voltage at the SELECT pin is in the range between
1.5 V and V
channels can be operational. If the SELECT pin is set to a
LOW voltage or grounded, then only channel 2 can
operate and the power amplifier of channel 1 will be in the
standby mode. In this case only the loudspeaker at
channel 2 can operate and the loudspeaker at channel 1
will be switched off. If the SELECT pin is set to a
HIGH level or connected to V
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
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
approx. 10 × C1 × (R1 + R2), so approximately 0.6 s. for
the values in Fig.4.
