GENERAL DESCRIPTION
The ADIS16350/5 iSensorTM 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, providing calibrated, digital inertial sensing. An SPI
interface and simple output register structure allow for easy
system interface and programming. The ADIS16355 provides
calibration over a temperature range of -40°C to +85°C.
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
