Note 5. Measured by Audio Precision, System Two. Averaging mode. Refer to the evaluation board manual.

Note 6. Figure 20 External LPF Circuit Example 2. 101dB for 16-bit data and 118dB for 20-bit data.

Note 7. Figure 20 External LPF Circuit Example 2. S/N does not depend on input data size.

Note 8. The voltage on (VREFH

− VREFL) is held +5V externally.

Note 9. Full-scale voltage(0dB). Output voltage scales with the voltage of (VREFHL/R

− VREFLL/R).

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

− (AOUT−) = ±2.8Vpp × (VREFHL/R − VREFLL/R)/5.

Note 10. Regarding Load Resistance, AC load is 1k

characteristics are sensitive to capacitive load that is connected to the output pin. Therefore the capacitive load

must be minimized.

Note 11. In the power down mode. The P/S pin = DVDD, and all other digital input pins including clock pins

(MCLK, BICK and LRCK) are held VSS4.
