The ADIS16350 iSensorTM provides complete tri axis inertial
sensing (both angular and linear motion) in a compact module
fully ready for system integration. With Analog Devices’
iMEMSTM sensor technology at its core, the ADIS16350
includes embedded processing for sensor calibration and
tuning. An SPI interface allows for simple system interface
and programming.
The SPI port provides access to the following embedded
sensors: X, Y, and Z axis angular rate; X, Y, and Z axis linear
acceleration; Internal Temperature; Power Supply; and an
Auxiliary analog input. The inertial sensors are precision
aligned across axis’, and are calibrated for offset and sensitivity.
System interfacing is simplified with the following additional
programmable features:
-

Guaranteed by design, not production tested.
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.

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.

Extended exposure to temperatures outside of the specified temperature range
of -40°C to +85°C can adversely affect the accuracy of the factory calibration. For
best accuracy, store the parts within the specified operating range of -40°C to
+85°C.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
