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 (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 KXTE9’s advanced, orientation-detection feature reports changes in
landscape, portrait, face-up, and face-down conditions. This sophisticated,
embedded algorithm eliminates the need for continuous data collection and
complex calculations by a microprocessor. With a few adjustable parameters, the screen-rotation algorithm can be optimized for an intuitive user
experience. In addition to orientation detection, the KXTE9 features an activity-monitoring function. This function reports changes in a device’s motion state, either moving (active) or not moving (inactive).
A highly-
manufacturable product with consistent product performance across use
conditions, the KXTE9 operates across a supply voltage of 1.8V to 3.6V DC.
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 and
environmental stress. The voltage is digitized by an on-board A/D converter
and is accessed via an inter-interated circuit (I2C).
