AOM-4544P-2

Overview

The AOM-4544P-2 is an omnidirectional analog condenser microphone manufactured by PUI Audio. It features a cylindrical metal housing with dimensions of 9.7 mm in diameter and length, and 4.5 mm in depth. The component operates at a supply voltage of 1.5 V and utilizes solder pin termination for circuit integration. Key electrical specifications include a sensitivity of -44 dB and an impedance of 2.2 kOhms.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Analog output signal type
• Solder pin termination method

Applications

• Consumer electronics audio input
• Industrial control systems
• Medical equipment monitoring

Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact electrical parameters. Datasheets may list variants such as AOM-4544P-NF-R or AOM-4544P-3-R with differing impedances or sensitivities. Ensure the selected part number matches the required circuit design constraints before procurement.

Selection Notes

Select this component for applications requiring low-voltage operation at 1.5 V. The 2.2 kOhm impedance and -44 dB sensitivity define the interface requirements. Verify mechanical fit within the 9.7 mm diameter constraint. Confirm that the analog output format aligns with the target amplifier input stage.

Part Context

This model belongs to the AOM series of omnidirectional microphones from PUI Audio. The series includes variants with different impedances and sensitivities, such as the AOM-4540P-R (-40 dB) and AOM-4544P-3-R (3 kOhm). These components share similar physical dimensions and operating voltages but differ in electrical characteristics.

Replacement Considerations

The AOM-4544P-NF-R shares identical dimensions and sensitivity but requires verification of the specific suffix meaning. The AOM-4544P-3-R offers higher impedance. Cross-referencing datasheets is essential to ensure electrical compatibility.
