PROPRIETARY TECHNOLOGY
These high-performance silicon micromachined linear
accelerometers and inclinometers consists of a sensor
element and an ASIC packaged in a 5x5x1.2mm Dual
Flat No-lead (DFN). The sensor element is fabricated
from single-crystal silicon with proprietary Deep Reactive
Ion Etching (DRIE) processes, and is protected from the
environment by a hermetically-sealed silicon cap wafer at
the wafer level.
The KXPA4 series is designed to provide a high signal-to-
noise ratio with excellent performance over temperature.
These sensors can accept supply voltages between 2.7V
and 5.25V. Sensitivity is factory programmable allowing
customization for applications requiring ±1.5g to ±6.0g
ranges. Sensor bandwidth is user-definable.
The sensor element functions on the principle of
differential capacitance. Acceleration causes displace-
ment of a silicon structure resulting in a change in ca-
pacitance. An ASIC, using a standard CMOS manufactur-
ing process, detects and transforms changes in capaci-
tance into an analog output voltage, which is proportional
to acceleration. The analog output is also accessed
through an on-board 3 channel multiplexor. The sense
element design utilizes common mode cancellation to
decrease errors from process variation and
environmental stress.
