Headphone Amplifier
_______________________________________________________________________________________
7
Note 5: DAC SNR measured from DAC inputs to OUTL and OUTR.
Note 6: Headphone amplifier SNR measured from line inputs to headphone outputs.
Note 7: GPIO is 100k
Ω to ground when DVDD < VOH < 3.6V.
Note 8: CB is in pF.
Note 9: fICLK derived by dividing fMCLK by 1, 2, 3, or 4. See the Registers and Bit Descriptions section.
