KXTIK-1004 Datasheet | Kionix

Description The KXTIK is a tri-axis +/-2g, +/-4g or +/-8g silicon micromachined accelerometer with integrated orientation, tap/double tap, and activity detecting algorithms. The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes mon mode cancellation to decrease errors from process variation, temperature, and environmental stress. The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device using a glass frit. A separate ASIC device packaged with the sense element provides signal conditioning, and intelligent user-programmable application algorithms. The accelerometer is delivered in a 3 x 3 x 0.9 mm LGA plastic package operating from a 1.8 - 3.6V DC supply. Voltage regulators are used to maintain constant internal operating voltages over the range of input supply voltages. This results in stable operating characteristics over the range of input supply voltages and virtually undetectable ratiometric error. I2C digital protocol is used to municate with the chip to configure and check for updates to the orientation, Directional Tap TM detection and activity monitoring algorithms. 36 Thornwood Dr. - Ithaca, NY 14850 tel: 607-257-1080 - fax:607-257-1146 .kionix. - info@kionix. © 2011 Kionix - All Rights Reserved 578-4177-1212201214 Page 1 of 55 Functional Diagram ± 2g / 4g / 8g Tri-axis Digital Accelerometer Specifications PART NUMBER: KXTIK-1004 Rev. 3 Dec-2012 X Sensor Y Sensor Charge A/D Amp Z Sensor Temp Sensor Digital Filter Vdd 14 IO Vdd 1 GND 12 I2C Digital Engine Motion Directional Detection Tap Tilt Position SCL SDA NC RSVD 36 Thornwood Dr. - Ithaca, NY 14850 tel: 607-257-1080 - fax:607-257-1146 .kionix. -...
