惯性测量单元, 2.4 V-3 V电源, LGA-16
is the world’s first complete consumer 6D MEMS Inertial Measurement Unit IMU with sensor fusion to specify system level orientation accuracy. When using the FIS1100 in combination with the supplied XKF3 9D sensor fusion, the system features an accurate ±3º pitch and roll orientation, and a ±5º yaw/heading typical specification. The FIS1100 incorporates a 3-axis Gyroscope and a 3-axis Accelerometer and can connect an external 3-axis magnetometer through an IC master thus forming a complete 9DOF system. The FIS1100 also incorporates an advanced vector Digital Signal Processor DSP motion co-processor called the AttitudeEngine™. The AttitudeEngine efficiently encodes high frequency motion at high internal sampling rates, preserving full accuracy across any output data rate. This enables the application to utilize low Output Data Rates ODR or on-demand host polling and still acquire accurate 3D motion data. The AttitudeEngine allows reducing the data processing and interrupt load on a host processor with no compromises in 3D motion tracking accuracy. The result is very low total system power in combination with high accuracy, which are essential to many portable and battery powered applications.
