• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta = 25 ° C; AVDD, DVDD = 4.75 ∼ 5.25V; fs = 44.1kHz; DEM = OFF; SLOW = “0”; PCM Mode)
Note 12. The passband and stopband frequencies scale with fs(system sampling rate). For example, PB=0.4535×fs
(@ ± 0.05dB), SB=0.546×fs.
Note 13. The calculating delay time which occurred by digital filtering. This time is from setting the 16/24bit data of both
channels to input register to the output of analog signal.
(Ta = 25°C; AVDD, DVDD = 4.75~5.25V; fs = 44.1kHz; DEM = OFF; SLOW = “1”; PCM Mode)
Note 14. The passband and stopband frequencies scale with fs. For example, PB = 0.185×fs (@ ± 0.04dB), SB = 0.888×fs.
(Ta = 25 ° C; AVDD, DVDD = 4.75 ∼ 5.25V)
Note 15. ACKSN pin has internal pull-down devices, nominally 100k Ω .
