Note: 4. Measured by UPD(ROHDE & SCHWARZ). Refer to the evaluation board manual.

5. 107dB at CCIR-ARM weighted

6. S/N is independent of input bit length.

7. VREFH is constantly +5.0V.

8. Full scale voltage (0dB). Output voltage scales with the voltage of VREFH pin.

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

±2.75Vpp*VREFH/5.0

9. AC load

10. PSR is applied to AVDD, DVDD with 1kHz, 100mVpp. VREFH pin is held a constant voltage.

11. All digital input pins including clock pins (MCLK, BICK and LRCK) are connected to DVSS.
