6-Axis Combo Sensors(3-Axis Accelerometer+ 3-Axis Gyroscope)

Kionix's advanced 6-axis combo sensors (3-Axis Accelerometer + 3-Axis Gyroscope) feature a low power architecture, I2C/ SPI digital communication, and an external input bus for controlling external sensors. Advanced buffering, power management, and synchronization are also provided. The KXG03 strikes an ideal balance between current consumption and noise performance to ensure excellent bias stability over temperature. The KXG03 operates at a current of less than 2mA, while the KXG08 utilizes an architecture that enables the lowest current consumption in the industry (0.6mA high resolution mode, 0.2mA low current mode), making it ideal for power-sensitive applications and always-ON operation. KXG03/ KXG07 are offered in a 16pin 3×3×0.9mm LGA package, while the KXG08 is available in a 14pin 2.5×3×0.9mm LGA package.
