IM70D122 | Digital high sensitivity XENSIV™ MEMS microphone enabling high quality audio capturing for laptop & tablet applications

Overview

High performance digital XENSIV^TM MEMS microphone IM70D122 makes the most out of Infineon´s Sealed Dual Membrane technology to meet a very high signal-to-noise ratio of 70 dB(A) and a very high sensitivity of -26 dBFS. Especially thanks to its high sensitivity and high SNR the IM70D122 is perfectly tailored for advanced audio capturing which can uplift the audio experience for laptops, tablets, cameras and conference systems. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level.
