High-temperature North Seeking MEMS Gyro For Gyro Tools(125°C)

Introduction

The ER-MG2-022 is a single-axis MEMS angular rate sensor (gyroscope) capable of measuring angular velocity up to a maximum of ±100°/s with digital output compliant to SPI slave mode 3 protocol. Angular rate data is presented as a 24-bit word.

The ER-MG2-022 is intended for north seeking applications. An advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG2-022 to operate in exceedingly harsh environments where shock and vibration are present.

The ER-MG2-022 is available in a hermetically sealed ceramic LCC surface mount package, and is capable of operating at 5V supply and a wide temperature range (−45°C to +125°C).
