The KXTC9 series is designed to provide a high signal-to-noise ratio with
excellent performance over temperature. These sensors can accept supply
voltages between 1.8V and 3.6V. Sensitivity is factory programmable allow-
ing customization for applications requiring from ±1.5g to ±6g ranges. Sev-
eral pre-set internal low pass filters can eliminate the need for external filter
capacitors. If the pre-set values are not optimal for an application, the sen-
sor bandwidth is user-definable with the use of external capacitors.
These high-performance silicon micromachined linear accelerometers and
inclinometers consist of a sensor element and an ASIC packaged in a
3x3x0.9mm Land Grid Array Dual (LGA). 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 at the wafer level.
The sensor element functions on the principle of differential capacitance.
Acceleration causes displacement of a silicon structure resulting in a change
in capacitance. An ASIC, fabricated using a standard CMOS manufacturing
process, detects and transforms changes in capacitance into an analog out-
put voltage, which is proportional to acceleration. The sense element design
utilizes common mode cancellation to decrease errors from process variation
and environmental stress.
