These high-performance silicon micromachined linear accelerometers and
inclinometers consist of a sensor element and an ASIC packaged in a
3x5x0.9mm 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 KXSS5 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 al-
lowing customization for applications requiring from ±2.5g to ±8.0g rang-
es. Sensor bandwidth is user-definable. Interrupts can be generated for
acceleration on any axis above a threshold value (Motion Interrupt) or for
acceleration on all three axes below a threshold value (Free-fall Interrupt).
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 out-
put voltage, which is proportional to acceleration. This voltage is digitized
by an on-board A/D converter and is accessed via an inter-integrated cir-
cuit (I2C) bus or serial peripheral interface (SPI).
