Terminology
Sensitivity
An angular rate gyroscope is a 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, the 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 (self-test) 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
