TDA8932B

Class-D audio amplifier

• 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.
