Procurement Notes
This component is officially marked as obsolete by the manufacturer. Procurement should focus on verifying availability through authorized distributors or secondary markets. Designers must consider the end-of-life status when planning long-term production runs. Verify specific ordering suffixes if available, as they may indicate packaging variations rather than functional changes. Confirm final availability before committing to design specifications.
Selection Notes
Select this part only for legacy system maintenance or repair where original specifications are mandatory. Due to its obsolete status, alternative modern equivalents should be evaluated for new designs. Ensure the required supply voltage remains within the 1V to 1.8V range. The 8-SOIC package dimensions must fit the existing PCB footprint without modification. Check for pin-compatible replacements if redesigning.
Part Context
The AS3430-EQFP belongs to the general-purpose audio amplifier category from ams OSRAM. It is distinct from the company's optical sensors and emitters. The 'EQFP' designation refers to the specific 8-SOIC package variant. This component serves niche audio applications requiring low-voltage operation and stereo output capabilities.
Replacement Considerations
No public confirmed substitute part numbers are listed in the provided documentation. Users should consult ams OSRAM technical support for current obsolescence management options or recommended cross-reference components for new designs.
