EVAL-KXD94-2802

KXD94 Series Accelerometers and Inclinometers FEATURES MARKETS Small Package - 5x5x1.2mm DFN Multiplexed Analog Output APPLICATIONS Automotive Internal 1KHz Low Pass Filter \\ Active Suspension Stability Control Telematics/GPS Low Noise Lead-free Solderability Excellent Temperature Performance High Shock Survivability Low Power Consumption User Definable Bandwidth Factory Programmable Offset and Sensitivity Industrial Platform Stabilization Drill Orientation Event Detection Vibration Analysis Appliance Monitoring Self-test Function PROPRIETARY TECHNOLOGY These high-performance silicon micromachined linear accelerometers and inclinometers 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 KXD94 series is designed to provide a high signal-to-noise ratio with excellent performance over temperature. These sensors can accept supply voltages between 2.5 – 5.25V. Sensitivity is factory programmable for applications requiring from ±5.0g to ±15.0g ranges. Sensor bandwidth is user-definable. 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, temperature, and environmental stress. 36 Thornwood Dr. - Ithaca, NY 14850 USA tel: 607-257-1080 - fax: 607-257-1146 - www.kionix.com - info@kionix.com “Kionix” is a registered trademark of Kionix, Inc.
