Introduction

High Performance Single Axis MEMS Gyroscope

Introduction
The ER-MG-069, High Performance Single Axis MEMS Gyroscope (Alternative of Gyro3300) is a single-axis MEMS angular rate sensor, which is capable of measuring angular velocity up to a maximum of ±400°/s and with digital output compliant to SPI slave mode 3 protocol. Angular rate data is presented as a 24-bit word.
The ER-MG-069 is intended for industrial, instrumentation, stabilization and other high performance applications. An advanced, differential sensor design resists the impact of linear acceleration, so that ER-MG-069 can operate in extremely harsh environments in the presence of impact and vibration.
The ER-MG-069 is available in a hermetically sealed ceramic LCC surface mount package and it is capable of operating at 5V supply and a wide temperature range (−40°C to +85°C).
