Note 3. DACL=DACR= “1”, ATTL=ATTR=0dB.
Note 4. AC Load
Note 5. Output voltage is proportional to VDD voltage. Vout = 0.58 x VDD(typ)@-3dBFS.
Note 6. PMDAC=PMHPL=PMHPR= “1”, MUTEN= “1” and HP-Amp output is off.
Note 7. All digital input pins including clock pins (MCLK, BICK and LRCK) are held at DVDD or DVSS. PDN pin is held
at VSS.
