When HP bit is “0”, output signal is muted and enter the Power-Save-Mode. Then HPL and HPR pins output HVCM
voltage. (Refer to Figure 24)
When HPP bit is “0”, Headphone-Amp is powered down perfectly. Then HPL and HPR pins go “L” (AGND). (Refer to
Figure 25)
When PD pin changes from “L” to “H” after power-up, HPL and HPR pins become Power-Save-Mode. In Power-
Save-Mode, output voltage of HPL and HPR pins gradually change from AGND to HVCM voltage by the time constants
of an internal resistor (R2: typ.10k
) and an external capacitor (C1). (Refer to Figure 24)
In case of entering the normal operation mode after that, HP bit changes from “0” to “1”.
In the Power-Down-Mode ( PD pin = “L” or HPP bit = “0”), output voltage of HPL and HPR pins gradually change from
AGND to HVCM voltage by the time constants of an internal resistor (R2:typ.10k
) and an external capacitor (C1).
(Refer to Figure 25)
