This digital MEMS microphone uses a PDM interface and is specified for a 67 dB signal-to-noise ratio with a -37 dBFS sensitivity. It operates from a 1.6 V to 3.465 V supply and draws 540 µA in high-performance mode, with a listed 170 µA low-power mode. The device has a 128 dBSPL acoustic overload point, a 10 Hz low-frequency roll-off, and IP57 dust and water resistance at component level. It is housed in a PG-TLGA-5-8 bottom-port package measuring 3.00 mm by 2.00 mm by 0.98 mm and is supplied in tape-and-reel packaging.
