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 KXPB5 series is designed to provide a high signal-to-noise ratio
with excellent performance over temperature. These sensors can ac-
cept 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 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.
This voltage is digitized by an on-board A/D converter and is accessed
via a serial peripheral interface (SPI).
