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 because the device

starts switching when the capacitor on pin HVPREF and the SE capacitors are completely

charged.

Output voltage buffers:

• 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 TDA8933 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.
