96kHz)
Normal Operation (RSTN pin = “H”, fs = 192kHz)
Power-Down Mode (RSTN pin = “L”) (Note 8)
Notes: 3. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
4. 100dB at 16bit data.
5. S/N does not depend on input bit length.
6. Full-scale voltage (0dB). Output voltage scales with the voltage of VDD,
AOUT (typ.@0dB) = 3.20Vpp × VDD/5.
7. For AC-load.
8. DIF1 pin is tied to VDD and the other all digital inputs including clock pins (MCLK, BICK and LRCK) are
tied to VSS.
