ANM-5254L-LW100-R

Overview

The ANM-5254L-LW100-R is an electret condenser microphone manufactured by PUI Audio, designed for analog audio applications with integrated noise-cancelling capabilities. It operates within a frequency range of 100 Hz to 10 kHz and features a sensitivity of -54 dB ±4dB. The device requires a DC supply voltage between 1.5 VDC and 10 VDC, drawing a current of 500 µA. Its electrical impedance is specified at 680 ohms. The component utilizes wire leads for termination and is constructed to function as a directional or noise-canceling acoustic sensor.

Feature Summary

• Integrated noise-cancelling functionality for improved signal clarity in noisy environments
• Electret condenser transducer technology for consistent analog audio output
• Wide operating voltage range supporting various low-power circuit designs

Applications

• Analog audio recording systems requiring noise reduction
• Communication devices utilizing electret microphone inputs
• Industrial equipment with ambient noise cancellation needs

Procurement Notes

Verify the specific sensitivity tolerance and impedance values against the latest manufacturer datasheet before integration. Confirm that the wire lead configuration matches the target PCB layout requirements. Ensure the power supply circuit provides stable voltage within the 1.5 VDC to 10 VDC range to maintain optimal performance and prevent damage to the internal FET amplifier.

Selection Notes

Select this component when analog noise cancellation is required without digital processing overhead. The wide voltage compatibility allows flexibility in power design. Consider the wire lead termination method during mechanical assembly planning. Verify that the 100 Hz to 10 kHz frequency response aligns with the specific audio bandwidth requirements of the application.

Part Context

This part belongs to PUI Audio's line of electret condenser microphones. It is distinct from their piezo benders and vibration motors. The model designation indicates specific electrical characteristics including sensitivity and impedance. It serves as a specialized acoustic input device for analog circuits rather than a general-purpose sound sensor.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed using exact electrical parameters such as 680 ohm impedance, -54 dB sensitivity, and 100 Hz to 10 kHz frequency range.
