Digital To Analog Converters Procurement Notes
Verify the component origin against the official Asahi Kasei Microdevices datasheet MS0247-E-02. Confirm the package type is 20-pin QFN with 0.5mm pitch. Ensure the operating temperature range matches the specified -40°C to +85°C. Check for any specific ordering suffixes that might indicate different packaging or variants.
Digital To Analog Converters Selection Notes
Select this component for low-power portable audio designs requiring integrated amplification. Ensure the system clock (MCLK) can be provided at 256fs, 384fs, or 512fs. Verify that the load impedance meets the minimum 16Ω requirement for the headphone amplifier. Consider the analog input resistance characteristics when designing the front-end circuitry.
Digital To Analog Converters Part Context
The AK4367VN is part of the AK4367 series from Asahi Kasei Microsystems. It is specifically the version housed in a 20-pin QFN package suitable for space-constrained portable applications. The 'VN' suffix typically denotes the specific package and temperature grade as listed in the ordering guide.
