MEMS (Micro-Electro-Mechanical System) Microphone is a microphone based on MEMS technology. Simply speaking, a capacitor is integrated on a micro-silicon wafer. It can be manufactured by using surface-mount technology (SMT). It is able to withstand high reflow temperature, easy to integrate with the CMOS process and other audio circuits. It has improved noise cancellation performance and good RF and EMI suppression. CRY6151B Electroacoustic Analyzer supports digital (PDM/I2S) and analog microphone testing, including parameters such as sensitivity, phase, distortion, SNR, and max. SPL. It meets laboratory testing requirements in many aspects. It also supports multi-channel acquisition and analysis, which can be integrated with programming and testing to improve productivity.
