Bosch BHI385 programmable smart IMU with on-sensor AI-powered analysis
Mouser is now stocking the BHI385 smart inertial measurement unit (IMU) from Bosch. The BHI385 is an intelligent sensor system that delivers accurate acceleration measurement up to ±28 g – enabling precise motion analysis for high-impact events across sports, fitness, and gaming. The sensor combines a gyroscope and accelerometer with embedded AI software and an integrated 32-bit microprocessor, creating a complete programmable system based on Bosch Sensortec’s field-proven IMU platform.
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.
Rohm has developed ultra-compact CMOS op amp delivering ultra-low circuit current
This IC is optimised to be applied as a measurement sensing amplifier in size-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors.
