POM-2740P

Microphones Overview

The POM-2740P is an electret condenser microphone manufactured by PUI Audio, Inc. It features an omnidirectional pickup pattern and analog output. The device operates within a voltage range of 2V to 10V. Key electrical specifications include a sensitivity of -40dB ±3dB and a signal-to-noise ratio of 60dB. The impedance is specified at 2.2 kOhms.

Microphones Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions.
• Analog output capability suitable for direct interfacing with audio processing circuits.
• Electret condenser transducer technology providing consistent performance.

Microphones Applications

• Voice recognition systems requiring clear audio input
• Consumer electronic devices needing compact microphone solutions
• Industrial control panels with voice command interfaces

Microphones Procurement Notes

Verify the specific suffix or variant required for your design, as datasheets may list related models like POM-2740P-C33-R with distinct characteristics such as directionality or impedance. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement plans to ensure regulatory adherence.

Microphones Selection Notes

Select this component when an omnidirectional response is necessary for ambient noise capture rather than directional isolation. Ensure the host circuit can support the 2V to 10V operating voltage range. Consider the 2.2 kOhm impedance when designing matching amplifier stages to optimize signal transfer efficiency.
