MM023802-3

Microphones Overview

The MM023802-3 is a MEMS microphone manufactured by DB Unlimited. It features an analog output type and omnidirectional directivity. The device operates within a frequency range of 100 Hz to 10,000 Hz. Its sensitivity is specified as -38 dB with a tolerance of ±3 dB. The signal-to-noise ratio is 61 dB. The component is supplied in a Tape & Reel (TR) package.

Microphones Feature Summary

• Utilizes MEMS technology for audio sensing
• Provides analog output signals
• Features omnidirectional sound pickup

Microphones Applications

• Audio input devices
• Voice recognition systems
• Consumer electronics audio modules

Microphones Procurement Notes

Verify the specific suffix or tape configuration when ordering, as distribution listings may reference cut tape or reel variants. Confirm the analog output requirement matches the system interface. Ensure the omnidirectional characteristic aligns with the acoustic design needs. Check for any specific RoHS compliance documentation if required by the target market regulations.

Microphones Selection Notes

Select this component when an analog interface is required rather than digital PDM. The -38 dB sensitivity offers a balanced response for general voice capture. The 61 dB SNR is suitable for standard communication applications. Consider the physical dimensions and mounting requirements associated with the TR packaging format during PCB layout.

Microphones Part Context

This part belongs to the DB Unlimited MEMS microphone portfolio. It serves as an alternative to other analog MEMS microphones in the market. The product line focuses on compact audio solutions for portable devices. DB Unlimited specializes in custom and standard electro-acoustic components.

Microphones Replacement Considerations

Direct substitutes must match the analog output type and similar sensitivity levels. Verify pin compatibility and package dimensions before substitution. Digital output microphones are not compatible replacements without interface changes.
