PRODUCT OVERVIEW
The Kionix KXTIK is a low power, high performance tri-axis
accelerometer with digital I2C output. The KXTIK features user-
selectable parameters including 8-bit or 12-bit modes, g-ranges
from ± 2g, 4g 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.
The KXTIK features a 16-pin package, making it pin compatible
with popular products on the market. The KXTIK also offers
enhanced embedded Screen Rotation, Directional Tap/Double
Tap, Orientation Detection and Low Power Motion Interrupt.
The KXTIK has an internal voltage regulator that allows
operation from 1.8 V to 3.6 V with an operating temperature
range of -40°C to +85°C.

1 Resolution and acceleration ranges are user selectable via I2C.
2 Resonance as defined by the dampened mechanical sensor.
3 User selectable through I2C.
4 User selectable; dependent on ODR and RES.
The performance parameters below are programmed and tested at 2.6 volts and T = 25°C. 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.
