KXPB5 SERIES
Tri-Axis, 1.5g - 6g, Multiplex and Digital (SPI) Output, 3x5x0-.9mm LGA
The KXPB5 series of linear accelerometers and inclinometers 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 ±6g ranges. Sensor bandwidth is user-definable.
These high-performance silicon-micromachined sensors 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 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).
