New IPX7-rated waterproof MEMS microphone

CUI Devices’ Audio Group has released a new waterproof MEMS microphone that is excellent for harsh environments. The CMM-3424DT-26165-TR MEMS microphone holds an IPX7 waterproof rating for applications where moisture and liquid ingress are an issue. Housed in a compact, surface mount package measuring 4mm x 3mm x 1mm, this waterproof MEMS microphone provides a digital PDM output and top port location.

This MEMS microphone provides designers with flexibility and a 100Hz to 10,000Hz operating frequency range and a working temperature range from -40C to 100C. The device also features omnidirectional directivity, a -26dB sensitivity rating, tight sensitivity tolerance of ±1dB, and an SNR of 65dBA. The model is also reflow solder compatible.
