MEMS MICROPHONE Digital PDM Descripción

High performance digital XENSIVTM MEMS microphone


Description

The IM69D120 is designed for applications where low self-noise (high SNR), wide dynamic range, low distortions

and a high acoustic overload point is required.

Infineon's Dual Backplate MEMS technology is based on a miniaturized symmetrical microphone design, similar

as utilized in studio condenser microphones, and results in high linearity of the output signal within a dynamic

range of 95dB. The microphone distortion does not exceed 1% even at sound pressure levels of 118dBSPL. The


flat frequency response ( 28Hz low-frequency roll-off) and tight manufacturing tolerance result in close phase

matching of the microphones, which is important for multi-microphone (array) applications.

With its low equivalent noise floor of 25dBSPL (SNR 69dB(A)) the microphone is no longer the limiting factor in

the audio signal chain and enables higher performance of voice recognition algorithms.

The digital microphone ASIC contains an extremely low-noise preamplifier and a high-performance sigma-delta


ADC. Different power modes can be selected in order to suit specific current consumption requirements.

Each IM69D120 microphone is calibrated with an advanced Infineon calibration algorithm, resulting in small

sensitivity tolerances (± 1dB). The phase response is tightly matched (± 2°) between microphones, in order to

support beamforming applications.
