Wide Dynamic Range, Miniature MEMs IMU Data Sheet ADIS16470 FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope, ±2000°/sec dynamic range
The ADIS16470 is a miniature MEMS inertial measurement
8°/hr in run bias stability
unit (IMU) that includes a triaxial gyroscope and a triaxial
0.008°/sec/√Hz rms rate noise density
accelerometer. Each inertial sensor in the ADIS16470 combines
Triaxial, digital accelerometer dynamic range: ±40 g
with signal conditioning that optimizes dynamic performance.
