Product Description
The KXTIK is a tri-axis +/-2g, +/-4g or +/-8g silicon
micromachined accelerometer with integrated orientation,
tap/double tap, and activity detecting algorithms. The sense
element is fabricated using Kionix’s proprietary plasma
micromachining process technology. Acceleration sensing is
based on the principle of a differential capacitance arising
from acceleration-induced motion of the sense element,
which further utilizes common mode cancellation to decrease
errors from process variation, temperature, and
environmental stress. The sense element is hermetically
sealed at the wafer level by bonding a second silicon lid
wafer to the device using a glass frit. A separate ASIC
device packaged with the sense element provides signal
conditioning, and intelligent user-programmable application
algorithms. The accelerometer is delivered in a 3 x 3 x 0.9
mm LGA plastic package operating from a 1.8 – 3.6V DC supply. Voltage regulators are used to
maintain constant internal operating voltages over the range of input supply voltages. This results in
stable operating characteristics over the range of input supply voltages and virtually undetectable
ratiometric error. I²C digital protocol is used to communicate with the chip to configure and check for
updates to the orientation, Directional Tap^TM detection and activity monitoring algorithms.
