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.

2 The MSB presents an exception to this parameter. The MSB clocks out on the falling edge of CS. The rest of the DOUT bits are clocked after the falling edge of SCLK and
are governed by this specification.
3 This parameter may need to be expanded to allow for proper capture of the LSB. After CS goes high, the DOUT line goes into a high impedance state.
