GENERAL DESCRIPTION
are calibrated for offset and sensitivity over the industrial
The ADIS16365 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.
temperature range of −40 to +85°C. An embedded controller
dynamically compensates for all major influences on the
sensors, thus maintaining highly accurate sensor outputs
without further testing, circuitry, or user intervention.
The following programmable features simplify system integra-
tion: in-system autobias calibration, digital filtering and sample
rate, self-test, power management, condition monitoring, and
auxiliary digital input/output.
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
This compact module is approximately 23 mm × 23 mm ×
23 mm and provides a convenient flex-based connector system.
