Product Description
The KXCJK is a tri-axis +/-2g, +/-4g or +/-8g silicon
micromachined accelerometer. 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 digital
communications. 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. The I²C digital
protocol is used to communicate with the chip to configure the part and monitor outputs.
