The IM70D122V01XTMA1 is a digital PDM MEMS microphone based on Infineon's Sealed Dual Membrane technology, delivering component-level IP57 water and dust resistance. The microphone features a bottom port acoustic opening and is designed for high-quality audio capture in applications such as laptops, tablets, conference systems, cameras, active noise cancellation (ANC) headphones, and voice-user-interface smart devices.
The microphone provides a 70dB(A) signal-to-noise ratio (SNR), a 122dBSPL acoustic overload point, and a 98dB dynamic range. The frequency response is flat with a low-frequency roll-off starting at 30Hz, typical sensitivity is -26dBFS (1kHz, 94 dBSPL), and total harmonic distortion (THD) is typically 0.25% (measured from the 2nd to 5th harmonics at 1kHz).
The component comes in a PG-TLGA-5-2 package, operates within a supply voltage range of 1.62 to 3.6V, and has an operating ambient temperature range of -40 to 85°C.
