Terminology
2.4.1
Sensitivity
An angular rate gyroscope is a device that produces a positive-going digital output for
counterclockwise rotation around the sensible 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.
2.4.2
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.
2.5
Sleep mode and power-down mode
The L3G462A enables advanced power saving functionalities thanks to the different
operating modes available. When the device is set in sleep mode configuration, the reading
chain is completely turned off, allowing low power consumption. In this condition the device
turn-on time is significantly reduced allowing simple external power cycling.
The user can select the desired operating mode through two dedicated pins (MS1 and
MS2).
2.6
Soldering information
The LGA package is compliant with the ECOPACK RoHS and “Green” standards.
It is qualified for soldering heat resistance according to JEDEC J-STD-020.
Leave “Pin 1 Indicator” unconnected during soldering.
Land pattern and soldering recommendations are available at www.st.com/mems.
