When this pin is Low , the audio amplifier is in differential mode. If a High level is applied, the configuration is in
Single−Ended Mode
Bypass capacitor pin which provides the common mode voltage (VP/2).
Positive output of the amplifier. In high impedance state when the device is in Single−Ended mode.
Positive analog supply of the cell.
Not connected.
Ground.
Audio Input Signal.
The device enters in shutdown mode when a low level is applied to this pin.
Negative output of the amplifier. This is the active output dedicated to a SE load when this configuration is
activated.
