Note 5. Measured by Audio Precision, System Two. Averaging mode. Refer to the evaluation board manual.
Note 6. By Figure 17. External LPF Circuit Example 2.101dB at 16bit data and 118dB at 20bit data.
Note 7. By Figure 17. External LPF Circuit Example 2. S/N does not depend on input bit length.
Note 8. The voltage on (VREFH
VREFL) is held +5V externally.
Note 9. Full-scale voltage(0dB). Output voltage scales with the voltage of (VREFH
VREFL).

Note 12. In the power-down mode. P/S pin = TTL pin = DVDD, and all other digital input pins including clock pins
(MCLK, BICK and LRCK) are held DVSS.
Note 13. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. VREFH pin is held +5V.
