Description

Infineon’s XENSIV™ MEMS analog differential microphone IM70A135V01 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.
