Product data sheet Rev. 04 — 18 December 2008 12 of 48 NXP Semiconductors 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. 9. Internal circuitry Table 7.
