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. |
