英飞凌发布新款MEMS麦克风:71.5 dB信噪比与IP57防护重塑音频体验
2025-10-20
Infineon Technologies recently expands its XENSIV ™ The MEMS microphone product line has launched two digital PDM microphones, IM72D128V and IM69D129F. The new product is based on Infineon’s Sealed Double Diaphragm (SDM) technology, achieving IP57 level dust and water resistance while balancing high sound quality, low power consumption, and strong robustness. Among them, the IM72D128V has a signal-to-noise ratio of up to 71.5 dB (A), specially designed for precise pickup in low-noise environments; The IM69D129F, with its ultra compact size of 3.5 × 2.65 × 0.98 mm ³, is suitable for portable devices with extremely limited space. Both achieve digital signal output through low-noise preamplifiers and Sigma Delta ADCs, providing reliable audio solutions for consumer electronics, industrial monitoring, and vehicle systems.
