Note 4. Measured by Audio Precision System Two. Refer to the evaluation board manual.
Note 5. 100dB at 16bit data.
Note 6. S/N does not depend on input bit length.
Note 7. Full scale voltage (0dB). Output voltage scales with the voltage of VREFH pin. AOUT (typ. @0dB) =
(AOUT+)-(AOUT-) = ±2.5Vpp×VREFH/5.0
Note 8. For AC-load. 4kΩ for DC-load
Note 9 AVDD=40mA(Typ), DVDD=12mA(Typ)@44.1kHz&5V, 16mA(Typ)@96kHz&5V
Note 10 AVDD=40mA(Typ), DVDD=22mA(Typ)@192kHz&5V
Note 11. All digital inputs including clock pins (MCLK, BICK and LRCK) are held DVDD or DVSS.
