Tri-Axis, User Selectable 2g, 4g, 8g, Digital (I2C) Output, 3x3x0.9mm LGA

The Kionix KXTI9 is a low power, high performance tri-axis accelerometer with digital I2C output.  The KXTI9 features user selectable parameters including 8 or 12 bit modes, g-ranges from +- 2, 4 or 8g, and Output Data Rates from 12.5 Hz to 800 Hz. A 252 byte FIFO/FILO buffer offers programmable watermark interrupt and provides a triggered low resolution or high resolution mode.

Pin and register compatible with Kionix’ popular KXTF9, the KXTI9 features enhanced embedded  Screen Rotation, Directional Tap/Double Tap, Orientation Detection and Low Power Motion Interrupt.

The KXTI9 has internal voltage regulators that allow operation from 1.8 V to 3.6 V and is delivered in a 3 x 3 x 0.9 mm, 10-pin, LGA package with an operating temperature range of -40°C to +85°C.
