IM70A135V01XTMA1

IM70A135V01XTMA1 is a high performance analogue XENSIV™ MEMS microphone. It is a compact size and high-performance microphone with a very high acoustic overload point of 135 dBSPL. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level. The small size makes this microphone especially suited for TWS earbud applications. Potential applications includes active noise cancellation (ANC) headphones and wireless earbuds (TWS), devices with voice user interface (VUI), smart speakers, home automation, IoT devices, high quality audio capturing, conference systems, cameras and camcorders, industrial or home monitoring with audio pattern detection.
