PUI Audio MEMS Microphones

PUI Audio MEMS Microphones feature a specialized preamplification ASIC that provides high sensitivity and high SNR output from a capacitive audio sensor in a small footprint. These high-performance microphones feature low distortion and high acoustic overload points, resulting in high dynamic range performance. The MEMS microphones offer competitive advantages over most microphones in the market, including ultra-low current consumption. These microphones are housed and packaged for surface mounting and high-temperature reflow assemblies. Key applications include security monitoring devices (breaking-glass detection), industrial devices (machine monitoring for predictive maintenance, in-cabin operator safety), microphone arrays, and consumer devices (smart IoT).
