Overview
The I3G4250DTR is a low-power 3-axis angular rate sensor developed by STMicroelectronics. It is designed to provide unprecedented stability at zero-rate level and sensitivity over temperature and time. The sensor includes a sensing element and an IC interface, which are manufactured using dedicated micromachining and CMOS processes, respectively. This allows for a high level of integration and precise matching of the sensing element's characteristics. The device communicates through standard SPI and I²C digital interfaces and is available in a plastic land grid array (LGA) package, operating within a temperature range of -40°C to +85°C.
