Description
The L2G2IS is a two-axis MEMS gyroscope for
optical image stabilization applications.
It includes a sensing element and an IC interface
capable of providing the measured angular rate to
the application through an SPI digital interface.
The unique sensing element is manufactured
using a dedicated micromachining process
developed by STMicroelectronics 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 characteristics of the sensing
element.
The L2G2IS is available in a plastic land grid
array (LGA) package and can operate over a
temperature range of -40 °C to +85 °C.
