KXP84 SERIES
Tri-axis, 1.5g - 6g, Digital (I2C or SPI) Output, 5x5x1.2mm DFN
The KXP84 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 2.7V and 5V. Sensitivity is factory programmable, allowing customization for applications requiring from ±1.5g to ±6g ranges. 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).
These high-performance silicon-micromachined linear sensors consist of a sensor element and an ASIC packaged in a 5x5x1.2mm Dual Flat No-lead (DFN). 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 an inter-integrated circuit (I2C) bus or serial peripheral interface (SPI).
