Product Description
The KXCJ9 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.
