Tri Axis Gyroscope & Accelerometer ADIS16350
GENERAL DESCRIPTION
The ADIS16350 iSensorTM provides complete tri axis inertial sensing (both angular and linear motion) in a compact module fully ready for system integration. With Analog Devices’ iMEMSTM sensor technology at its core, the ADIS16350 includes embedded processing for sensor calibration and tuning. An SPI interface allows for simple system interface and programming. The SPI port provides access to the following embedded sensors: X, Y, and Z axis angular rate; X, Y, and Z axis linear acceleration; Internal Temperature; Power Supply; and an Auxiliary analog input. The inertial sensors are precision aligned across axis’, and are calibrated for offset and sensitivity. System interfacing is simplified with the following additional programmable features: In-system Bias Auto Calibration Digital Filtering and Sample Rate Self Test Power Management Condition Monitoring Auxiliary Digital I/O
APPLICATIONS
Guidance and control Platform control and stabilization Motion control and analysis Inertial Measurement Units General Navigation Image stabilization Robotics
The ultra compact module measures 22.7mmx23.2mmx22.9mm, plus mounting extensions.
