• Manufacturer Part Number: AK4440
• Description: 192kHz 24-Bit 8ch DAC with 2Vrms Output
• Manufacturer: AKM [Asahi Kasei Microsystems]

(Ta=25°C; VDD=AVDD = +5.0V; fs=44.1kHz; BICK=64fs; Signal Frequency=1kHz; 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 AVDD,
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. The P/S pin is tied to VDD and the all other digital inputs including clock pins (MCLK, BICK and LRCK) are
MS1088-E-01
