Notes: 3. Measured by AD725C(SHIBASOKU). Averaging mode. Refer to the eva board manual.
4. Full-scale voltage(0dB). When summing the differential outputs by unity gain,
AOUT(typ.@0dB)=(AOUT+)-(AOUT-)= ±2.80Vpp*VREF/5.
5. In the power-down mode, all digital input pins including clock pins(XTI,,BICK,LRCK) are
held DVDD or DVSS.
6. PSR is applied to AVDD,DVDD with 1kHz, 100mVpp.
