10. Full-scale voltage(0dB). Output voltage scales with the voltage of (VREFH-VREFL).
11. For AC-load. 1k for DC-load.
12. In the power-down mode. P/S = DVDD, and all other digital input pins including clock pins (MCLK, BICK and
13. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. VREFH pin is held +5V.
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.
