    ER-MG-056 Economical MEMS Gyroscope

    Introduction
    The ER-MG-056, a low cost Tactical Grade MEMS Gyro with 1 deg/hr bias of instability and 0.25°/√h of angular random walk, 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-MG-056 is intended for industrial, instrumentation, stabilization, and other high performance applications. An advanced, differential sensor design rejects the influence of linear acceleration, enabling the ER-MG-056 to operate in exceedingly harsh environments where shock and vibration are present.
    The ER-MG-056 is available in a hermetically sealed ceramic LCC surface mount package, and is capable of operating at 5V supply and a wide temperature range (−40°C to +85°C).
