Overview
The A3G4250D 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 communicates the measured angular rate through a standard SPI digital interface or an I2C-compatible interface. The sensing element is manufactured using a dedicated micro-machining process, while the IC interface is produced using a CMOS process, allowing for high integration and precision in matching the sensing element characteristics.
The A3G4250D operates within a temperature range of -40 °C to +85 °C and is available in a plastic land grid array (LGA) package.
