Microphones Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official documentation to confirm package compliance and reflow soldering guarantees. Ensure the operating environment remains within the specified -30 °C to +100 °C range. Confirm that the analog output requirements match the downstream circuitry impedance and voltage levels before finalizing procurement.

Microphones Selection Notes

Select this component when a low-power, omnidirectional MEMS microphone with analog output is required. It is suitable for applications needing operation up to 3.6 V and extended industrial temperature ranges. Consider the 100 Hz to 10 kHz frequency response for standard voice band applications. Verify compatibility with surface-mount assembly processes.

Microphones Part Context

This part belongs to STMicroelectronics' MEMS microphone portfolio, designed for compact audio sensing solutions. It integrates a silicon-based sensing element into a surface-mount package.
