Terminology
Sensitivity
An angular rate gyroscope is device that produces a positive-going digital output for
counterclockwise rotation around the sensitive axis considered. Sensitivity describes the
gain of the sensor and can be determined by applying a defined angular velocity to it. This
value changes very little over temperature and time.
Zero-rate level
Zero-rate level describes the actual output signal if there is no angular rate present. The
zero-rate level of precise MEMS sensors is, to some extent, a result of stress to the sensor
and therefore zero-rate level can slightly change after mounting the sensor onto a printed
circuit board or after exposing it to extensive mechanical stress. This value changes very
little over temperature and time.
Self-test
Self-test allows testing of the mechanical and electric part of the sensor, allowing the
seismic mass to be moved by means of an electrostatic test-force. When self-test is
activated by the IC, an actuation force is applied to the sensor, emulating a definite Coriolis
force. In this case the sensor output exhibits an output change.
When ST is active, the device output level is given by the algebraic sum of the signals
produced by the velocity acting on the sensor and by the electrostatic test-force.
Soldering information
