• Manufacturer Part Number: ak4368
• Description: Dac With Built-in Pll & Hp-amp
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
(Ta=25°C; AVDD, DVDD, PVDD, HVDD=1.6 ∼ 3.6V; fs=44.1kHz; De-emphasis = “OFF”)
Note 12. BOOST OFF (BST1-0 bit = “00”)
Note 13. The passband and stopband frequencies scale with fs.
Note 14. This is the calculated delay time caused by digital filtering. This time is measured from the setting of the 24bit
Note 15. DAC
Note 16. MIN
Note 17. These frequency responses scale with fs. If high-level signal is input, the output clips at low frequency.
