Note: 10. Full-scale output voltage by DAC (0dBFS). Output voltage of DAC scales with the voltage of VD,
Stereo output (typ@0dBFS) = 2Vrms × VD/5 when volume#0=volume#1=0dB. The output must not exceed 3Vrms.
Note: 11. The PSR is applied to VD with 1kHz, 100mV.

Note: 12. The passband and stopband frequencies scale with fs.
e.g.) PB=0.4535×fs (@
±
0.05dB), SB=0.546×fs.
Note: 13. The calculating delay time which occurred by digital filtering. This time is from setting the 16/18/24bit data of
both channels to input register to the output of analog signal.
