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. Kionixs XAC sensor provides outstanding stability with a market-leading combination of improved shock, reflow, and thermal performance. KX023 Accelerometer 3x3x0.9mm Accelerometer with FIFO/FILO Buffer The performance parameters below are programmed and tested at 2.6 volts and T = 25C. The device can accept supply voltages from 1.8V to 3.6V. Due to internal voltage regulators, there should be minimal change with supply voltage variations.
