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.
