PROPRIETARY TECHNOLOGY
These high-performance silicon micromachined linear accelerometers
and inclinometers consist of a sensor element and an ASIC packaged in
a 3x5x0.9 mm Land Grid Array (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 KXRB5 series is designed to provide a high signal-to-noise ratio
with excellent performance over temperature. These sensors can accept supply voltages between 2.5V and 5.25V. Sensitivity is factory
programmable allowing customization for applications requiring from
1.5g to 6.0g ranges. Sensor bandwidth is user-definable. The auxiliary input to the A/D converter and multiplexer minimizes the need for
external A/D converters.
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.
