AOW-6540L-R

Overview

The AOW-6540L-R is an omnidirectional analog microphone manufactured by PUI Audio, Inc. It operates within a frequency range of 50 Hz to 16 kHz and requires a rated voltage of 1.5 VDC, supporting up to 10 VDC. The device features an output impedance of 2 kohms at 1 kHz and a sensitivity of -40 ±3 dB (referenced as 0 dB = 1V/Pa). It draws a current of 300 µA and utilizes solder pads for termination.

Feature Summary

• Omnidirectional acoustic pickup pattern
• Analog signal output capability
• Low power consumption design

Applications

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

Procurement Notes

Verify the specific datasheet version for the AOW-6540L-R to confirm exact sensitivity tolerances and operating voltage limits. Ensure compatibility with the target circuit's biasing requirements, as the component specifies a 1.5 VDC rated voltage. Confirm that the solder pad termination style matches the printed circuit board layout constraints.

Selection Notes

Select this component when an omnidirectional response is required for compact audio sensing applications. The low operating voltage and current make it suitable for battery-powered devices. Verify that the 2 kohm output impedance aligns with the input stage of the connected amplifier or microcontroller interface.

Part Context

This microphone belongs to the PUI Audio lineup of standard audio components. The manufacturer specializes in transducers and indicators for various electronic sectors. This specific model represents a basic analog solution for general-purpose sound detection tasks.

Replacement Considerations

The AOM-6742L-R is a documented alternative from the same manufacturer. Note that the AOM-6742L-R has a sensitivity of -42 dB and a 2.2 kohm impedance, which differs from the AOW-6540L-R specifications.
