Analog Devices 3-Axis Surface Mount Sensor, ML, SPI, 20-Pin

Inertia sensor ICs combine a number of sensors into one package to more accurately measure changes in velocity and orientation. Also known as measuring six degrees of freedom due to measuring both rotating and acceleration and can be used for dead reckoning and other positional calculations. They may also include accelerometers, gyroscopes, magnetometers, temperature sensors and inclinometers to compensate for drift.
