Preliminary data sheet
8.7 Output voltage buffers
When pin POWERUP is set HIGH, the half supply output voltage buffers are switched on
in asymmetrical supply configuration. The start-up will be pop free since the device starts
switching when the capacitor on pin HVPREF and the SE capacitors are completely
charged.

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 TDA8932 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.
