KMX62-1031-FR ROHM

PART NUMBER: 1200uT Tri-axis Digital Magnetometer/ KMX62-1031 2g/4g/8g/16g Tri-axis Digital Rev. 4.0 Accelerometer Specifications 20-Dec-2017 Product Description KMX62 is a 6 Degrees-of-Freedom inertial sensor system that 2 features 16-bit digital outputs accessed through I C communication. The KMX62 sensor consists of a tri-axial magnetometer plus a tri- axial accelerometer coupled with an ASIC. It is packaged in a 3 x 3 x 0.9 mm Land Grid Array (LGA) package. The ASIC is realized in standard 0.18m CMOS technology and features flexible user programmable 2g / 4g / 8g / 16g full scale range for the accelerometer and 1200T full scale range for the magnetometer. Accelerometer and Magnetometer data can be accumulated in an internal 384-byte FIFO buffer and transmitted to the application processor. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration- induced motion of the sense element, which utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress. Capacitance changes are amplified and converted into digital signals which are processed by a dedicated digital signal processing unit. The digital signal processor applies filtering, bias, and sensitivity adjustments, as well as temperature compensation. Magnetic sensing is based on the principle of magnetic impedance. The magnetic sensor detects very small magnetic fields by passing an electric pulse through a special electron spin aligned amorphous wire. Due to the high Curie temperature of the wire, the sensors thermal performance shows excellent stability. Noise performance is excellent with bias stability over temperature. Bias errors resulting from assembly can be trimmed digitally by the user. These sensors can accept supply voltages between 1.7V and 3.6V, and digital communication voltages between 1.2V and 3.6V. 36 Thornwood Dr. Ithaca, NY 14850 2017 Kionix All Rights Reserved tel:
