IM69D130V01XTSA1

Microphones Overview

The IM69D130V01XTSA1 is a digital MEMS microphone featuring dual backplate technology for high linearity and low distortion. It operates within a voltage range of 1.62 V to 3.6 V with a supply current of 980 uA. The device provides a signal-to-noise ratio of 69 dBA, a dynamic range of 105 dB, and an acoustic overload point of 128 dB SPL. Sensitivity is -36 dB ±1 dB at 94 dB SPL. It supports PDM output with a frequency response from 20 Hz to 20 kHz. The component measures 4 mm x 3 mm x 1.2 mm in an LLGA-5 package.

Microphones Feature Summary

• Dual backplate MEMS technology ensures high linearity and low distortion similar to studio condenser microphones.
• Tight manufacturing tolerances enable close phase matching for multi-microphone array applications.
• Advanced calibration algorithm results in small sensitivity and phase variations between units.
• Low equivalent noise floor prevents the microphone from limiting audio signal chain performance.

Microphones Applications

• Voice recognition systems requiring high SNR
• Multi-microphone beamforming arrays
• Smart home appliances and IoT devices
• Home entertainment audio interfaces

Microphones Procurement Notes

Verify the specific suffix XTSA1 against official Infineon documentation to confirm packaging type and reel specifications. Ensure compatibility with the target system's power supply voltage limits and PDM interface requirements. Cross-reference the RoHS status and moisture sensitivity level before integration into the production workflow.

Microphones Selection Notes

Select this component when low self-noise and wide dynamic range are critical for voice processing accuracy. The tight phase matching makes it suitable for spatial audio and beamforming implementations. Consider the 1.62 V to 3.6 V operating range for flexible power design options in portable electronics.
