GENERAL DESCRIPTION
The ADIS16354 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, providing 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 accelera-
tion; internal temperature; power supply; and auxiliary analog
input. The inertial sensors are precision-aligned across axes,
and are calibrated for offset and sensitivity over a temperature
range of −20°C to +70°C. An embedded controller dynamically
