IM70A135V01XTMA1

Microphones Overview

The IM70A135V01XTMA1 is an omnidirectional MEMS microphone from Infineon Technologies, featuring analog output and a top sound port. It operates within a supply voltage range of 2.3 V to 3 V and delivers a sensitivity of -38 dB with a signal-to-noise ratio of 70 dB. The device supports a frequency range of 37 Hz to 15 kHz and withstands sound pressure levels up to 135 dBSPL. Packaged in a compact LGA-5 footprint measuring 3.5 mm x 2.65 mm x 1 mm, it functions reliably between -40°C and +85°C while maintaining IP57 protection.

Microphones Feature Summary

• Provides high-fidelity analog audio capture with a 70 dB signal-to-noise ratio for clear voice recognition.
• Features robust environmental resilience with IP57 rating against dust and water immersion.
• Supports high acoustic input handling up to 135 dBSPL without distortion.

Microphones Applications

• Voice-controlled smart home devices
• Wearable health monitoring equipment
• Industrial IoT sensor nodes

Microphones Procurement Notes

Verify the specific suffix XTMA1 to confirm tape-and-reel packaging configuration. Ensure the design accommodates the LGA-5 package dimensions and top-port acoustic requirements. Confirm compliance with RoHS directives and AEC-Q103 qualification standards if automotive usage is intended. Validate that the host circuit supports the 2.3 V to 3 V operating voltage range.

Microphones Selection Notes

Select this component when analog interface compatibility is required rather than digital PDM outputs. Choose this model for applications demanding high sound pressure tolerance and environmental sealing. Consider the 70 dB SNR for standard voice pickup needs. Evaluate the 3.5 mm x 2.65 mm footprint against available PCB space constraints.

Microphones Part Context

This part belongs to the XENSIV MEMS microphone family, designed for reliable acoustic sensing. It complements digital variants like the IM70D series by offering direct analog signal output. The product line emphasizes miniaturization and durability for embedded audio systems.

Microphones Replacement Considerations

Check for other analog MEMS microphones with similar -38 dB sensitivity and 70 dB SNR. Verify pinout compatibility for the LGA-5 package before substituting. Ensure replacement parts meet the same IP57 and temperature range specifications.
