Datasheet Kionix KX112-1042

Part NumberKX112-1042

Tri-Axis, User Selectable ± 2g, 4g, 8g, Digital (I2C/SPI) Output, Integrated FIFO/FILO buffer, 2x2x0.6mm LGA

The KX112 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 KX112 also offers accelerometer outputs with up to 16-bit resolution for greater precision. User-selectable parameters include ± 2 g, 4 g or 8 g ranges and Output Data Rates (ODR) with programmable high-pass and low-pass filters. It is packaged in an ultra-small, 12-pin, 2x2x0.6 mm LGA plastic package.
