Pins HVP1 and HVP2: The time required for charging the SE capacitor depends on its
value. The half supply voltage output is disabled when the TDA8932B is used in a
symmetrical supply application.
Pin HVPREF: This output voltage reference buffer charges the capacitor on pin
HVPREF.
Pin INREF: This output voltage reference buffer charges the input reference capacitor
on pin INREF. Pin INREF applies the bias voltage for the inputs.
