NJU7181RB1-TE1, Nisshinbo Micro Devices

The New Japan Radio NJU7181 series is signal level sensor system IC. It sends a High flag to the microprocessor or other equipment's whenever it detects the existence of the audio signal. The product includes a delay circuit which allows the IC continue to hold the flag after the absence of the audio signal. This holding time can be adjusted with external capacitor. Operating Voltage is 0.9 to 5.5V Low Operating Current Delay circuit for long Recovery time Adjustable Recovery time by external capacitor Adjustable Input Sensitivity by external resistance CMOS Technology

IM72D128V01XTMA1, Infineon

The Infineon digital microphone is an ultra-high performance digital PDM MEMS microphone designed for applications which require a very high SNR (low self-noise) and low distortion (high AOP) and which is also IP57 robust to dust and water. Best-in-class signal-to-noise ratio (SNR) of 72dB(A) enables far field and low volume audio pick-up. The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications. Component level IP57 water and dust resistant Dynamic range of 106dB Acoustic overload point at 128dBSPL Signal to noise ratio of 72dB(A) SNR

IM69D120V01XTSA1, Infineon

The Infineon high performance digital XENSIV MEMS microphone is used in a 16 bit audio signal chain, the full SNR performance would not be realized as the noise floor will be limited by the system dynamic range. IM69D120 has been specifically designed to preserve 69dB(A) SNR in a 16 bit system. This is achieved by increasing the microphone sensitivity to -26dBFS, and reducing the acoustic overload point to 120dBSPL. High fidelity and far field audio recording Ultra-low group delay for latency-critical applications No analogue components required
