Infineon expands XENSIV MEMS microphone lineup
Infineon has expanded its XENSIV MEMS microphone lineup with the introduction of the IM72D128V and IM69D129F, two innovative digital PDM microphones designed for exceptional audio performance, energy efficiency, and robustness. Leveraging Infineon’s proprietary Sealed Dual Membrane (SDM) technology, both microphones achieve a high level of robustness against water and dust (IP57), making them suitable for use in demanding environments.
TI unveils the industry’s most sensitive in-plane Hall-effect switch
Texas Instruments has introduced the industry’s most sensitive in-plane Hall-effect switch for position sensing, offering engineers a cost-effective, user-friendly alternative to magnetoresistive sensors. TI’s TMAG5134 Hall-effect switch features an integrated a magnetic concentrator, enabling it to detect magnetic fields as weak as 1mT in applications such as door and window sensors, personal electronics, home appliances, and more. This level of sensitivity allows for the use of smaller magnets, further reducing system-level costs. Additionally, the TMAG5134’s in-plane sensing capability enables it to detect magnetic fields parallel or horizontal to a printed circuit board, giving engineers greater design flexibility.
