Product Description
The KX003-1077 is a tri-axis 2g, 4g, 8g, or 16g silicon
micromachined accelerometer. The sense element is fabricated using
Kionixs 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 2 x 2 x 0.9 mm LGA plastic package operating from a 1.71V 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
2
undetectable ratiometric error. The I C digital protocol is used to communicate with the chip to configure
the part and monitor outputs.
