GENERAL DESCRIPTION
The ADIS16385 iSensor® devices are complete inertial systems that include a triaxis gyroscope and triaxis accelerometer. Each sensor in the ADIS16385 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements. The yaw-axis gyroscope offers a 4× improvement in noise and in-run bias stability for applications that have greater requirements on one axis.
