• Manufacturer Part Number: ak4569
• Description: 20-bit Stereo Codec With Ipga & Hp-amp
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta=25°C; AVDD, DVDD, HVDD=2.5 ∼ 3.6V; fs=44.1kHz; DEM=OFF; BOOST=OFF)
Note 14. BOOST OFF (BST1-0 = “00”)
Note 15. The passband and stopband frequencies scale with fs.
Note 16. This is the calculated delay time caused by digital filtering. This time is measured from the input of analog signal
Note 17. DACL
Note 18. These frequency responses scale with fs. If high-level signal is input, the AK4569 clips at low frequency.

For example (DAC), PB=0.44*fs(@±0.1dB), SB=0.57*fs(@−59dB).
to setting the 20 bit data of both channels on input register to the output register of ADC. This time also includes
group delay of HPF. For DAC, this time is from setting the 20 bit data of both channels on input register to the
output of analog signal.
