AOM-4544L-R

Overview

The PUI Audio AOM-4544L-R is an analog omnidirectional electret condenser microphone designed for audio signal capture. It features a circular shape with a diameter of 9.7 mm and operates within a frequency range of 30 Hz to 15 kHz. The device requires a supply voltage between 1.5 V and 10 V and delivers a sensitivity of -44 dB ±3 dB. It utilizes solder pads for termination and provides a signal-to-noise ratio of 60 dB.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Analog output signal generation
• Wide operating voltage tolerance

Applications

• Consumer electronics audio input
• Industrial control voice interfaces
• Medical equipment monitoring

Procurement Notes

Verify the specific suffix designation, as 'L' variants may differ from standard 'P' versions regarding termination style or packaging. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the selected variant matches the required solder pad configuration for the target PCB layout.

Selection Notes

Select this component when an omnidirectional response is required for general sound capture rather than directional focusing. The wide voltage range allows flexibility in power supply design across various low-voltage digital systems. Verify that the 60 dB SNR meets the noise floor requirements of the specific application environment.

Part Context

This model belongs to the AOM series of microphones manufactured by PUI Audio, Inc., a company specializing in audio components such as transducers and speakers. The series includes various configurations tailored for different mounting and electrical interface needs within electronic assemblies.

Replacement Considerations

The AOM-4544P-NF-R is a related variant within the same product family. Engineers should verify if the termination type and exact sensitivity tolerances of the substitute part are compatible with the existing circuit design.
