L3G3200D
MEMS motion sensor:
three-axis digital output gyroscope
Preliminary data
Description
The L3G3200D is a low-power three-axis angular rate sensor.
It includes a sensing element and an IC interface able to provide the measured angular rate to the external world through a digital interface
2
(I
C/SPI).
The sensing element is manufactured using a dedicated micromachining process developed by ST to produce inertial sensors and actuators on silicon wafers. The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics.
Applications
Gaming and virtual reality input devices
Motion control with MMI (man-machine
interface)
GPS navigation systems
Appliances and robotics
±2000 dps and is capable of measuring rates with a user selectable bandwidth.
The L3G3200D is available in a plastic land grid array (LGA) package and can operate within a temperature range of -40 °C to +85 °C.

2.6 Terminology

2.6.1 Sensitivity

An angular rate gyroscope is 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.

2.6.2 Zero-rate level

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

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.
