General Description

The IM73D122V01 is an ultra-high performance digital PDM MEMS microphone designed for applications which require a very high SNR (low self-noise) and high sensitivity and which is also IP57 robust to dust and water.

Best-in-class signal-to-noise ratio (SNR) of 73dB(A) enables far field and low volume audio pick-up.

The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications.

Overview

IM73D122V01 Ultra-low noise high sensitivity digital XENSIVTM MEMS.
