Applications information
Mode selection
Pin STANDBY selects the operating mode, namely standby or play.
During the turn on/off sequence, there are four operational states: standby, pre-charge,
mute and play. The pre-charge and mute states are two internal transient states to set up
the normal operating condition and to reduce the speaker pop noise.
Table 6.
An internal pull-down resistor on pin STANDBY ensures that the default mode is standby.
Gain setting
The close loop gain is set by pins GAIN0 and GAIN1 as shown below in
setting is implemented by changing the feedback resistors of the amplifiers.
Table 7.
Internal pull-down resistors on pins GAIN0 and GAIN1 ensure that the default gain is 6 dB.

In standby mode, all the circuits are turned off and there is very low leakage current.
In play mode, the amplifiers are powered up.
