Microphones Procurement Notes

Verify the current production status as the component is listed as End-of-Life (EOL). Confirm availability through authorized distributors or secondary market channels. Ensure compatibility with Sn/Pb and Pb-free soldering processes during integration. Review final datasheet revisions for any last-time buy information or specific handling requirements before procurement planning.

Microphones Selection Notes

Select this component for designs requiring high signal-to-noise ratio in small form factors. The bottom port configuration facilitates optimal acoustic coupling in tight enclosures. Consider the single-ended interface for simplified circuit design compared to differential outputs. Verify that the 3.50 × 2.65 mm footprint fits the PCB layout constraints.

Microphones Part Context

This analog MEMS microphone belongs to TDK InvenSense's sensor portfolio, targeting consumer electronics and IoT markets. It complements digital microphone offerings by providing an analog interface option for legacy or specific system architectures requiring direct analog signal processing.

Microphones Replacement Considerations

Due to the End-of-Life status, identify alternative analog MEMS microphones with similar dimensions (-38 dBV sensitivity, 3.50x2.65mm package) and frequency response. Evaluate pin-compatible replacements if available to minimize PCB redesign efforts.
