ADIS16385:  Six Degrees of Freedom Inertial Sensor

The ADIS16385 iSensor® device is a complete inertial system that includes a tri-axis gyroscope and tri-axis 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 gyro-scope offers a 4× improvement in noise and in-run bias stability for applications that have greater requirements on one axis.

The ADIS16385 provides a simple, cost-effective method for integrating accurate, multiaxis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The SPI and register structure provide a simple interface for data collection and configuration control.

The ADIS16385 has a compatible pinout for systems that currently use ADIS1635x, ADIS1636x, and ADIS1640x IMU products. It comes in a module that is approximately 36 mm × 47 mm × 39 mm and has a standard connector interface.
