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

(Ta = 25°C; VDD = 4.5 ∼ 5.5V; fs = 44.1kHz)
Note 8. The passband and stopband frequencies scale with fs(system sampling rate). For example, PB=0.4535×fs
Note 9. Calculated delay time caused by digital filter. This time is measured from setting the 16/24bit data of both
