Microphones Procurement Notes

Verify the manufacturer designation as Goertek Microelectronics Inc. Confirm the specific model suffix matches the required frequency and voltage specifications. Ensure compatibility with the intended PCB layout for solder pad termination. Cross-reference official datasheets for environmental ratings and handling precautions.

Microphones Selection Notes

Select this component when an omnidirectional analog microphone is required for low-voltage applications. The 1.5 V to 3.6 V operating range suits portable devices. Verify that the 100 Hz to 8 kHz bandwidth meets the target audio fidelity requirements. Consider the solder pad package for assembly methods.

Microphones Part Context

This part belongs to the Goertek Microelectronics analog MEMS microphone series. It shares similar acoustic characteristics with models like the S14OB381-057 but differs in frequency response limits and minimum operating voltage. The series focuses on compact, high-quality audio sensing solutions.

Microphones Replacement Considerations

The S14OB381-057 offers comparable sensitivity but extends the upper frequency limit to 10 kHz and requires a higher minimum voltage. The S08OB381-045 provides a similar 1.5 V to 3.6 V range and 8 kHz bandwidth. Evaluate these alternatives based on specific frequency response needs.
