Application note
Fig 3. Simplified SE application TDA8932B/33(B) (asymmetrical supply)
(1) The TDA8933T device requires a 1 MΩ resistor in parallel with the bootstrap capacitor Cbo. TDA8932BT, TDA8932BTW
SLEEP control
MUTE control
and TDA8933BTW devices do not require a 1 MΩ resistor.

The TDA8932B/33(B) can operate also from a symmetrical supply (see
three half supply voltage buffers are disabled. HVPREF (Pin 11), HVP1 (pin 30) and HVP2
(pin 19) should be connected to ground when supplied from a symmetrical supply.
