GENERAL DESCRIPTION
The ADIS16350/5 iSensor^TM 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

the MEMS sensors; thus maintaining highly accurate sensor
outputs without further testing, circuitry, or user intervention.
System integration is simplified with the following additional
programmable features:
• In-system auto bias 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.
