Tri-Axis Gyroscope/ Tri-Axis Accelerometer - KXG03

The KXG03 is an advanced 6-axis accelerometer/gyroscope combination device that features a low-power architecture with 2mA maximum operating current, I2C/SPI digital communications, an auxiliary bus to control and buffer external sensors and advanced buffering, power management and synchronization features. The KXG03 strikes a balance between current consumption and noise performance with excellent bias stability over temperature. Sensor bandwidth is user-selectable. The KXG03 is packaged in a single 3 x 3 x 0.9 mm, 16-pin, LGA package.
