High-Precision Tri-Axis Inertial Sensor

The ADIS16350/ADIS16355 iSensor™ is a complete triple axis gyroscope and triple axis accelerometer inertial sensing system. This sensor combines the Analog Devices, Inc.,iMEMS® and mixed signal processing technology to produce a highly integrated solution that provides calibrated, digital inertial sensing. An SPI interface and simple output register structure allow for easy access to data and configuration controls.

The SPI port provides access to the following embedded sensors: X-, Y-, and Z-axis angular rates; X-, Y-, and Z-axis linear acceleration; internal temperature; power supply; and auxiliary analog input. The inertial sensors are precision-aligned across axes, and are calibrated for offset and sensitivity. An embedded controller dynamically compensates for all major influences on the MEMS sensors, thus maintaining highly accurate sensor outputs without further testing, circuitry, or user intervention.

The following programmable features simplify system integration: in-system autobias calibration, digital filtering and sample rate, self-test, power management, condition monitoring, and auxiliary digital input/output.

This compact module is approximately 23 mm × 23 mm × 23 mm and provides a convenient flex-based connector system.
