• Manufacturer Part Number: AK4388A
• Description: 192kHz 24-Bit 2ch ?? DAC
• Manufacturer: AKM [Asahi Kasei Microsystems]

(Ta = 25°C; VDD = 5.0V; fs = 44.1kHz; BICK = 64fs; Signal Frequency = 1kHz; 24bit Input Data; Measurement
frequency = 20Hz ∼ 20kHz; R
Note 2. Measured by Audio Precision (System Two). Refer to the evaluation board manual.
Note 3. 100dB at 16bit data.
Note 4. S/N does not depend on input bit length.
Note 5. Full-scale voltage (0dB). Output voltage scales with the voltage of VDD, AOUT (typ.@0dB) = 3.20Vpp ×
VDD/5.
Note 6. For AC-load.
Note 7. The DIF1 pin is held to VDD and the other all digital inputs including clock pins (MCLK, BICK and LRCK) are
MS1008-E-02
