Product Details

ER-MG2-1000 High Performance MEMS Gyro For Guidance 


Introduction

The ER-MG2-1000 is a single-axis MEMS angular rate sensor (gyroscope) capable of measuring angular velocity up to a maximum of ±400°/s with digital output compliant to SPI slave mode 3 protocol. Angular rate data is presented as a 24-bit word.

The ER-MG2-1000 is intended for Guidance and other high porformance applications. An advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG2-1000 to operate in exceedingly harsh environments where shock and vibration are present.

The ER-MG2-1000 is available in a hermetically sealed ceramic LCC surface mount package, and is capable of operating at 5 V supply and a wide temperature range (−50°C to +85°C).
