KXRB5 SERIES
Tri-Axis, 1.5g - 6g, Ultra Low Noise Digital (SPI) and Multiplexed Analog, 3x5x0.9mm LGA
The KXRB5 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. The auxiliary input to the A/D converter and multiplexer minimizes the need for external A/D converters.
These high-performance silicon micromachined sensors 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 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.
