KX023-1025-FR

KX023 Accelerometer 3x3x0.9mm Accelerometer with FIFO/FILO Buffer FEATURES APPLICATIONS  3x3x0.9mm LGA package  Full-featured algorithm engine including: o Tap detection, orientation detection, activity monitoring, and embedded motion wake-up algorithms  Low current consumption in all modes: o 0.9 μA in standby, o 10 μA at normal resolution, and o 145 μA at high resolution  Two interrupt registers  User-configurable, embedded wake-up function to conserve battery power  Internal voltage regulator to maintain constant internal operating voltages throughout the 1.8 - 3.6V input supply range         PRODUCT OVERVIEW The KX023 accelerometer delivers unparalleled flexibility, enabling you to optimize power and noise performance to meet your product design needs. By simply selecting the output data rate (ODR) and amount of oversampling for data averaging you can tune power and noise performance to meet the needs of your specific application. In addition, the 3-axis KX023 offers I2C/SPI output and an integrated FIFO/FILO buffer that features a wide range of embedded functionality, including tap detection, orientation, activity, and wake-up algorithms. Kionix’s XAC sensor provides outstanding stability with a market-leading combination of improved shock, reflow, and thermal performance.
