Microphones Procurement Notes

Verify the specific revision status and RoHS compliance details prior to procurement, as manufacturing updates may occur. Confirm that the solder pad termination method aligns with your assembly process capabilities. Ensure the operating voltage requirements of your circuit design remain strictly within the 0.9 V to 1.6 V specification to prevent device damage or performance degradation during integration.

Microphones Selection Notes

Select this component when an omnidirectional response is required for consistent audio input from multiple directions. The low operating voltage makes it appropriate for battery-powered applications where power efficiency is critical. Consider the 100 Hz to 4.8 kHz bandwidth limitation if high-fidelity audio reproduction outside this range is necessary for the target application.
