Headphone Amplifier Output (HPL/HPR pins)
Headphone amplifiers are operated by positive and negative power that is supplied from internal charge
pump circuit. The VEE2 pin output the negative voltage generated by the internal charge pump circuit
from CVDD. This charge pump circuit is switched between VDD mode and 1/2VDD mode by the output
level of the headphone amplifiers. The headphone amplifier output is single-ended and centered on
HPGND (0 V). A capacitor for AC coupling is not necessary. The load resistance is 14.4
Ω (Min.). The
output power is 10 mW when 0 dBFS, RL = 32Ω, AVDD = CVDD = 1.8 V and HPG = 4 dB, and it is 25
mW when 0 dBFS, RL = 32Ω, AVDD = 1.8 V and HPG = 0 dB. Ground loop noise cancelling function for
headphone amplifier is available by connecting the HPGND pin to the ground of the jack.

• Class-G Mode Switching Level:
VDD
→ 1/2 VDD: < 1.05 mW at both channels (@ CVDD = 1.8 V, R
L = 32Ω)
1/2 VDD
→ VDD: ≥ 1.05 mW at either channel (@ CVDD = 1.8 V, R
L = 32Ω)
When the charge pump operation mode is changed to VDD mode from 1/2 VDD mode, an internal
counter for holding VDD mode starts (Table 19). The charge pump changes to 1/2 VDD mode if the output
signal level is lower than the switching level and 1/2 VDD mode detection time that is set by LVDTM[2:0]
bits is passed after VDD mode hold time is finished.
