Procurement Notes

Verify component status carefully before procurement. Official sources indicate this specific part number may be obsolete or no longer in active manufacturing. Confirm availability through authorized distributors and check for valid replacement alternatives if current stock is unavailable. Ensure datasheet versions match the specific revision required for your design.

Selection Notes

Select this component for applications requiring low power consumption and small form factor. The analog output interface requires appropriate amplification circuitry. Verify that the operating voltage range aligns with the system's power rails. Consider the 100 Hz lower frequency limit when evaluating suitability for bass-heavy audio capture scenarios.

Part Context

This MEMS microphone belongs to the SP series of miniature silicon microphones. Originally developed by Knowles Acoustics, the product line was acquired by Syntiant. These components are designed for high-performance audio sensing in mobile and IoT devices, offering reliable performance in compact packages.

Replacement Considerations

Official sources list AMM-3742-2-T by PUI Audio as a similar available substitute. Verify pin compatibility and acoustic specifications before substitution.
