PROPRIETARY TECHNOLOGY
These high-performance silicon micromachined linear accelerometers and
inclinometers consist 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 at the wafer level.
The KXD94 series is designed to provide a high signal-to-noise ratio with
excellent performance over temperature. These sensors can accept supply
voltages between 2.5 – 5.25V.
Sensitivity is factory programmable for
applications requiring from ±5.0g to ±15.0g ranges. Sensor bandwidth is
user-definable.
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, using a standard CMOS manufacturing
process, detects and transforms changes in capacitance into an analog output voltage, which is proportional to acceleration. The sense element design utilizes common mode cancellation to decrease errors from process
variation, temperature, and environmental stress.
