GSY-MG2-300/400 High Precision Navigation MEMS Gyroscope
Introduction
The GSY-MG2-300/400 High Precision Navigation MEMS Gyroscope is a single-axis MEMS angular rate sensor (gyroscope), which can measure the maximum angular velocity of ±400°/s, and the digital output conforms to SPI slave mode 3 protocol. Angular rate data is presented as a 24-bit word.
The GSY-MG2-300/400 is intended for navigation, and other high performance applications. Advanced differential sensor design rejects the influence of linear acceleration, enabling the GSY-MG2-300/400 to operate in exceedingly harsh environments where shock and vibration are present.
The GSY-MG2-300/400 is available in a hermetically sealed ceramic LCC surface mount package, and is capable of operating at 5V supply and a wide temperature range (−50°C to +85°C).
