EVAL-KX023-1025
KX023-1025 ACCELEROMETER

The KX023 is a robust, low-power, I2C/SPI, 3-axis accelerometer with 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. The KX023 also offers accelerometer outputs with up to 16-bit resolution for greater precision. User-selectable parameters include 2g, 4g or 8g ranges and Output Data Rates (ODR) with programmable high-pass and low-pass filters. It is packaged in a 16-pin, 3x3x0.9mm LGA plastic package.
