The IM72D128VV01 is an ultra-high-performance digital PDM MEMS microphone designed for applications requiring extremely high signal-to-noise ratio (low SNR) and low distortion (high AOP), as well as IP57-rated dust and water resistance.
Best-in-class signal-to-noise ratio (SNR) of 72dB(A) for far-field and low-volume audio pickup. Flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerances improve performance in multi-microphone (array) applications.
The digital microphone ASIC includes an extremely low-noise preamplifier and a high-performance sigma-delta ADC. Different power modes can be selected to meet specific clock frequency and current consumption requirements.
Each IM72D128VV01 microphone is calibrated using advanced Infineon calibration algorithms, resulting in low sensitivity tolerances (± 1dB).
