Note 4. Measured by Audio Precision System Two. Refer to the evaluation board manual.
Note 5. 100dB at 16bit data.
Note 6. S/N does not depend on input bit length.
Note 7. Full scale voltage (0dB). Output voltage scales with the voltage of AVDD pin. AOUT (typ. @0dB) =
3.4Vpp×AVDD/5.0
Note 8. For AC-load.
Note 9. P/S pin is tied to DVDD and the other all digital input pins including clock pins (MCLK, BICK, LRCK) are tied
to DVSS.
