Note 22. Maximum input voltage is proportional to AVDD voltage. (0.6 x AVDD) Vpp
Note 23. DAC 0dBFS Output (Both L/R channels and the same phase) and OATT = 0dB.
Note 24. Maximum output voltage is proportional to AVDD voltage. (0.6 x AVDD) Vpp
Note 25. MPWR pin supplies 0mA.
Note 26. As VCOM bit = “1”, power supply current of HVDD is 0.8mA (typ.).
Note 27. In power-down, all digital input pins including clock (MCLK, BCLK and LRCK) pins are held at “DVDD” or
“DVSS”. PDN pin is held at “DVSS”.
* 0dBV = 1Vrms = 2.83Vpp
