AOM-6742P-2

Overview

The AOM-6742P-2 is an omnidirectional electret condenser microphone manufactured by PUI Audio. It features a sensitivity of -42 dB and operates within a frequency range of 30 Hz to 15 kHz. The device has an impedance of 2.2 kohms and requires a supply voltage between 1.5 VDC and 10 VDC, with a typical current consumption of 500 µA. Its physical dimensions are 9.7 mm in diameter and length, with a depth of 4.5 mm. The unit utilizes solder pin termination for circuit integration.

Feature Summary

• Omnidirectional acoustic pickup pattern for uniform sound capture from all directions
• Electret condenser transducer technology providing analog audio output
• Wide operating voltage range supporting flexible power supply designs

Applications

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

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as AOM-6742P-2-R may differ in packaging or minor specifications. Confirm that the required impedance and sensitivity tolerances align with your circuit design requirements before finalizing procurement. Ensure compatibility with the intended operating voltage range of 1.5 VDC to 10 VDC.

Selection Notes

Select this component when an omnidirectional response is required for general-purpose voice or ambient sound detection. The 2.2 kohm impedance and -42 dB sensitivity are suitable for standard pre-amplifier stages. Consider the physical footprint of 9.7 mm x 9.7 mm for space-constrained enclosures requiring through-hole or surface-mount solder pin connections.
