• Manufacturer Part Number: AK4425A
• Description: 192kHz 24-Bit Stereo ?? DAC with 2Vrms Output
• Manufacturer: AKM [Asahi Kasei Microsystems]

(Ta = 25°C; VDD=AVDD = +5.0V; fs = 44.1 kHz; BICK = 64fs; Signal Frequency = 1 kHz;
24bit Input Data; Measurement frequency = 20Hz ∼ 20kHz; R
Note 4. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
Note 5. 98dB for 16bit input data
Note 6. S/N does not depend on input data size.
Note 7. Full-scale voltage (0dB). Output voltage is proportional to the voltage of VDD,
Note 8. In case of driving capacitive load, inset a resistor between the output pin and the capacitive load.
Note 9. The current into VDD and AVDD.
Note 10. All digital inputs including clock pins (MCLK, BICK and LRCK) are fixed to VSS1(VSS2) or VDD(AVDD).
