KXTC9 Series Accelerometers and Inclinometers FEATURES MARKETS APPLICATIONS Ultra-small Package - 3x3x0.9mm LGA Analog Output Cell Phones and Handheld PDAs Low Power Consumption Gesture Recognition Factory-programmable Internal Low Pass Filter Ultra-mobile PCs/Laptops/Hard Disk Drives Low Noise Free-fall Detection Lead-free Solderability Game Controllers & Computer Peripherals Excellent Temperature Performance Inclination and Tilt Sensing High Shock Survivability Userdefinable Bandwidth Cameras and Video Equipment Factory-programmable Offset and Sensitivity Image Stabilization Self-test Function Sports Diagnostic Equipment/Pedometers Static or Dynamic Acceleration PROPRIETARY TECHNOLOGY The KXTC9 series is designed to provide a high signal-to-noise ratio with excellent performance over temperature. These sensors can accept supply voltages between 1.8V and 3.6V. Sensitivity is factory programmable allow- ing customization for applications requiring from 1.5g to 6g ranges. Sev- eral pre-set internal low pass filters can eliminate the need for external filter capacitors. If the pre-set values are not optimal for an application, the sen- sor bandwidth is user-definable with the use of external capacitors. These high-performance silicon micromachined linear accelerometers and inclinometers consist of a sensor element and an ASIC packaged in a 3x3x0.9mm Land Grid Array Dual (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, fabricated using a standard CMOS manufacturing process, detects and transforms changes in capacitance into an analog out- put voltage, which is proportional to acceleration. The sense element design utilizes common mode cancellation to decrease errors from process variation 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.
