Terminology

2.6.1

Sensitivity

An angular rate gyroscope is a device that produces a positive-going analog 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.

2.6.2

Zero-rate level

Zero-rate level describes the actual output signal if there is no angular rate present. 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.

2.7

Soldering information

The LGA package is compliant with the ECOPACK

, RoHS and “Green” standard.

It is qualified for soldering heat resistance according to JEDEC J-STD-020.

Leave “Pin 1 Indicator” unconnected during soldering.
