L20G20IS Ultra-compact two-axis gyroscope for optical image stabilization Datasheet - production data Applications Optical image stabilization Description The L20G20IS 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 LGA-12 (2.0 x 2.0 x 0.7 mm) using a dedicated micromachining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers. Features The IC interface is manufactured using a CMOS process that allows a high level of integration to 100 dps / 200 dps full-scale range design a dedicated circuit which is trimmed to 5 degree phase delay better match the characteristics of the sensing 3.8 mdps/(Hz) rate noise density element. Wide supply voltage range: 1.7 V to 3.6 V The L20G20IS is available in a plastic land grid array (LGA) package and can operate over a Low-voltage compatible IOs temperature range of -40 C to +85 C. 3- and 4-wire SPI digital interface Embedded temperature sensor Embedded self-test Integrated low-pass filters with user-selectable bandwidth Power-down and sleep modes for smart power saving ECOPACK , RoHS and Green compliant Table 1.
