Microphones Procurement Notes

Verify the specific suffix (e.g., -7) against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging options. Ensure compatibility with the target operating temperature range of -40°C to +105°C during system integration planning.

Microphones Selection Notes

Select this component when a low-profile, omnidirectional analog MEMS microphone is required. The 300-ohm impedance and 2V operation are key constraints for interface circuitry design. Compare frequency response limits against application requirements.

Microphones Part Context

This part belongs to the Precise series of MEMS microphones from DB Unlimited. It utilizes silicon-based technology to deliver consistent acoustic performance in a miniature form factor designed for modern electronic assemblies.

Microphones Replacement Considerations

Consult official substitution lists for equivalent omnidirectional MEMS microphones with similar 300-ohm impedance and 2V supply requirements. Verify pinout and dimensional compatibility before replacing.
