Note 2. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
Note 3. 98dB at 16bit data
Note 4. S/N does not depend on input bit length.
Note 5. Full-scale voltage (0dB). Output voltage is proportional to the voltage of VDD,
AOUT (typ.@0dB, GAIN =0dB) = 2Vrms × VDD/3.3.
Note 6. In case of driving capacitive load, inset the resister between output pin and the capacitive load.
Note 7. The current into VDD pin or HVDD pin
Note 8. All digital inputs including clock pins (MCLK, BICK and LRCK) are fixed to VSS or VDD, and GAIN pin is
fixed to VSS or open.
