IM70D122V01XTMA1

IM70D122V01XTMA1 is a high-performance digital PDM MEMS microphone designed to meet a very high signal-to-noise ratio of 70dB(A). Especially due to its high sensitivity and high SNR the IM70D122V01 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 Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level. The potential application includes high-quality audio capturing, laptops and tablets, conference systems, cameras and camcorders, active noise cancellation (ANC) headphones and earphones, devices with voice user interface (VUI), smart speakers, home automation, IOT devices, smartphones and mobile devices, industrial or home monitoring with audio pattern detection.
