XENSIV™ MEMS microphones - low self-noise (SNR), wide dynamic range, low distortions, high acoustic overload point

 

IM69D130 is a high performance digital MEMS microphone making use of Infineon’s Dual Backplate MEMS technology to deliver 105dB dynamic range and high output linearity up to 130dBSPL. The application benefits are crystal clear audio signals, extended pick-up distance and sensitivity to both soft and loud signals - from whispered speech to rock concerts.

The Infineon Audiohub Nano enables the evaluation of Infineon digital PDM XENSIV™ MEMS microphones.

Features

• 69 dB(A) signal-to-noise ratio
• Below 1 percent distortions at 128 dBSPL (AOP - 130 dBSPL)
• Digital (PDM) interface with 6 μs group delay at 1 kHz
• Tight sensitivity (-36 ±1 dB) and phase (± 2 deg) tolerances
• 28 Hz low frequency roll-off

 

Benefits

• High fidelity and far field audio recording
• Matched, noise and distortion free audio signals for advanced audio signal processing
• Ultra-low group delay for latency-critical applications
• No analog components required
