KXTF9-4100 ± 2g / 4g / 8g Tri-axis Digital Accelerometer Specifications
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. I2C interface is used to communicate to
the chip to configure and check updates to the orientation, Directional TapTM detection and activity
monitoring algorithms.
