EM-9767P

Microphones Overview

The EM-9767P is an omnidirectional electret condenser microphone manufactured by Soberton Inc. It operates within a voltage range of 1 V to 10 V and features a circular shape with a diameter of 9.7 mm. The device provides analog output with a frequency response spanning 50 Hz to 10 kHz. Key electrical specifications include a sensitivity of -42 dB ±3 dB at 94 dB SPL, an output impedance of 2.2 kΩ, and a signal-to-noise ratio of 58 dB. It draws a working current of 500 uA and utilizes PC pins for termination.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology providing analog audio output
• Integrated internal capacitor for stable operation

Microphones Applications

• General purpose voice recording devices
• Consumer electronics audio input modules
• Telecommunication equipment microphones

Microphones Procurement Notes

Verify the specific suffix (e.g., -44) if precise sensitivity matching is required, as variants exist. Confirm package compatibility with PCB layout. Ensure supply chain sources provide official datasheets to validate active status and exact pin configurations before integration into production designs.

Microphones Selection Notes

Select this component when an omnidirectional response is necessary for ambient sound capture. The 9.7 mm diameter suits compact enclosures. Consider the 50 Hz to 10 kHz frequency range suitability for voice applications rather than high-fidelity music. Verify power supply constraints align with the 1 V to 10 V operating range.

Microphones Part Context

This part belongs to the EM series of electret condenser microphones from Soberton Inc. It shares design similarities with models like the EM-9745P but differs in specific sensitivity and dimensional parameters. The series is characterized by standard PC pin termination and circular housing formats commonly used in mass-produced audio hardware.

Microphones Replacement Considerations

The EM-9767P-44 is a documented variant within the same product line. It maintains identical physical dimensions and electrical interfaces but offers a sensitivity of -44 dB ±3 dB compared to the standard -42 dB. Substitution requires verification that the sensitivity difference meets system gain requirements.
