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

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

•

Auxiliary digital input/output

This compact module is approximately 23 mm × 23 mm ×

23 mm and provides a convenient flex-based connector system.
