L3G4200D

L3G4200D Description

The L3G4200D from STMicroelectronics is a 3-axis digital MEMS gyroscope designed for high-performance motion sensing applications. It operates within a 2.4V to 3.6V supply range, consuming 6.1 mA of current, and offers selectable full-scale ranges of ±250°/s, ±500°/s, and ±2000°/s with adjustable sensitivity (8.75 to 70 LSB/(°/s)). The device supports I2C and SPI interfaces for seamless integration into digital systems and features a bandwidth range of 100Hz to 800Hz, making it suitable for both low-power and high-frequency applications. Its 16-pin LGA package ensures compactness, while RoHS3 compliance and REACH unaffected status highlight its environmental suitability.
