Notes: 5. At 44.1kHz, measured by Audio Precision, System Two. Averaging mode.
At 96kHz and 192kHz, 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 Figure13. 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. 1kW 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.
