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 word length.

Note 7. Full scale voltage (0dB). Output voltage scales with the voltage of the AVDD pin. AOUT (typ. @0dB) =

3.4Vpp×AVDD/5.0

Note 8. For AC-load.

Note 9. The P/S pin is tied to DVDD and the other all digital input pins including clock pins (MCLK, BICK, LRCK) are

tied to DVSS.
