Microphones Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration when sourcing. Confirm that the component status aligns with project longevity requirements, as availability may vary. Ensure the ordering part number matches the exact electrical specifications required for the target application interface.

Microphones Selection Notes

Select this component for designs requiring analog output with extended ultrasonic bandwidth beyond standard audio ranges. Consider the low current draw for power-sensitive implementations. Verify compatibility with the system's supply voltage range and ensure adequate RF shielding if operating in high-interference environments due to the analog nature of the output.

Microphones Part Context

This part belongs to STMicroelectronics' MEMS microphone portfolio, specifically designed for industrial and specialized audio sensing. It complements other analog MEMS solutions by offering extended frequency capabilities. The product line focuses on providing reliable acoustic sensing for non-standard audio applications requiring high durability and performance.

Microphones Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's catalog that maintain the 80 kHz bandwidth specification. Verify that any substitute maintains the 1.52 V to 3.6 V operating range and similar sensitivity metrics to ensure circuit compatibility without redesign.
