Notes: 5. At 44.1kHz, measured by Audio Precision, System Two. Averaging mode.

At 96kHz, measured by ROHDE & SCHWARZ, UPD. Averaging mode.

Refer to the eva board manual.

6. 101dB at 16bit data and 116dB at 20bit data.

7. By Figure12. External LPF Circuit Example 2.

8. S/N does not depend on input bit length.

9. The voltage on (VREFH-VREFL) is held +5V externally.

10. Full-scale voltage (0dB). Output voltage scales with the voltage of (VREFH-VREFL).

AOUT (typ.@0dB) = (AOUT+) - (AOUT-) =

±2.4Vpp×(VREFH-VREFL)/5.

11. For AC-load. 1k

W for DC-load.

12. In the power-down mode. P/S = DVDD, and all other digital input pins including clock pins (MCLK, BICK and

LRCK) are held DVSS.

13. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. VREFH pin is held +5V.
