ADCs/DACs - Special Purpose Procurement Notes

The AK5394AVS is officially marked as obsolete and no longer manufactured by Asahi Kasei Microdevices. Verification of current availability should rely on distributor stock lists rather than direct manufacturer orders. Buyers must confirm the specific revision suffix, such as AVS, as functional changes are not guaranteed by suffix variations alone. Cross-referencing with approved replacement parts is recommended for new designs.

ADCs/DACs - Special Purpose Selection Notes

Select this component only for legacy system maintenance or repair where pin compatibility is critical. For new designs, consider the AK5572EN as a similar alternative from the same manufacturer. Ensure the application requires the specific 216 kHz maximum sampling rate and 28-SOP footprint before procurement, as newer generations may offer higher performance in different packages.

ADCs/DACs - Special Purpose Part Context

The AK5394AVS belongs to the AK5394A product family, which focuses on super high-performance audio conversion. It is part of Asahi Kasei's portfolio of specialized audio ADCs designed for professional applications requiring high dynamic range and low distortion at standard and high-resolution audio sample rates.

ADCs/DACs - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers include the AK5572EN from Asahi Kasei Microdevices. The AD1877JRZ from Analog Devices Inc. is also listed as a similar alternative.
