KXP94 SERIES
Tri-axis, 1g-5g, Multiplexed Analog, 5x5x1.2mm DFN
The KXP94 series of 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 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. The analog output is also accessed through an on-board four-channel multiplexer. The sense element design utilizes common mode cancellation to decrease errors from process variation and environmental stress.
