    Introduction

    ER-MG-057 High Accuracy Single-Axis MEMS Gyro

    Introduction
    ER-MG-057 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.
    ER-MG-057 is intended for industry, instrumentation, stabilization, and other high performance applications. An advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG-057 to operate in exceedingly harsh environments where shock and vibration are present.
    ER-MG-057 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 +85°C).
