KXCJB-1041 ROHM

PART NUMBER: 2g / 4g / 8g Tri-axis Digital KXCJB-1041 Rev. 1.0 Accelerometer Specifications Feb-2015 Product Description The KXCJB is a thin package tri-axis +/-2g, +/-4g or +/-8g silicon micromachined accelerometer. The sense element is fabricated using Kionixs 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 common 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 digital communications. The accelerometer is delivered in a very thin 3 x 3 x 0.45 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 2 undetectable ratiometric error. The I C digital protocol is used to communicate with the chip to configure the part and monitor outputs. 36 Thornwood Dr. Ithaca, NY 14850 2015 Kionix All Rights Reserved tel: 607-257-1080 fax:607-257-1146 www.kionix.com - info kionix.com Page 1 of 31 PART NUMBER: 2g / 4g / 8g Tri-axis Digital KXCJB-1041 Rev. 1.0 Accelerometer Specifications Feb-2015 Functional Diagram X Sensor Y Charge A/ D Sensor Amp Z Sensor Digital 5 Vdd Filter 2 I C 1 IO Vdd Digital Engine 4 GND 6 8 9 10 7 RSVD ADDR SCL SDA INT 36 Thornwood Dr. Ithaca, NY 14850 2015 Kionix All Rights Reserved tel: 607-257-1080 fax:607-257-1146 www.kionix.com - info kionix.com Page 2 of 31
