Description

The L3G4IS is the first three-axis MEMS

gyroscope that enables both user interface and

image stabilization applications at the same time.

Thanks to two different independent reading

chains and digital interfaces, the L3G4IS delivers

previously unseen levels of flexibility to the end

user.

Each reading chain and the corresponding full

scale can be activated by powering two separate

pins, the internal ASIC blocks automatically detect

and enable the selected device configuration.

The unique sensing element is manufactured

using a dedicated micro-machining process

developed by STMicroelectronics to produce

inertial sensors and actuators on silicon wafers.

The L3G4IS is available in a plastic land grid array

(LGA) package and can operate within a

temperature range of -30 °C to +85 °C.
