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

(Ta = 25°C; VDD=AVDD = +4.5 ∼ +5.5V; fs = 44.1 kHz; DEM = OFF; SLOW = “0”)
Note 11. The passband and stopband frequencies scale with fs(system sampling rate).
Note 12. Calculated delay time caused by digital filter. This time is measured from setting the 16/24bit data
