CM02M-03S38-MA-5

Overview

The CM02M-03S38-MA-5 is an analog omnidirectional MEMS microphone manufactured by Challenge Electronics. It operates within a voltage range of 1.6 V to 3.6 V and features a frequency response spanning from 100 Hz to 20 kHz. The device exhibits a sensitivity of -38 dB ±1 dB at 94 dB SPL. Designed for surface-mount applications, it utilizes solder pads for connection and is packaged in cut tape format for automated assembly processes.

Feature Summary

Omnidirectional acoustic design for uniform sound capture
MEMS silicon construction for durability
Analog output signal generation

Applications

Speech recognition systems
General audio recording
Consumer electronics audio input

Procurement Notes

Verify the specific suffix MA-5 against official datasheets to confirm pinout and sensitivity tolerances. Ensure compatibility with 1.6 V to 3.6 V supply rails. Confirm surface-mount footprint dimensions match PCB layout requirements before ordering.

Selection Notes

Select this component when an omnidirectional analog MEMS microphone is required for low-voltage operation. The -38 dB sensitivity suits standard audio interfaces. Verify that the 100 Hz to 20 kHz bandwidth meets application needs without additional filtering.

Part Context

This part belongs to the Challenge Electronics CM02M series of analog MEMS microphones. It shares the same form factor and basic functionality as variants like the CM02M-03S38-MA-3, differing primarily in packaging or specific manufacturing batch characteristics defined by the manufacturer.

Replacement Considerations

The CM02M-03S38-MA-3 is a documented variant within the same product line. Verify if functional differences exist between the MA-5 and MA-3 suffixes before substitution.
