The ADXRS642 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc., surface-micromachining process to make a functionally complete and low cost angular rate sensor integrated with all of the required electronic components, including analog filters, digital outputs, temperature sensor, and self-test function.
The ADXRS642 is a complete angular‑rate gyroscope from Analog Devices, designed for industrial applications such as inertial measurement units and platform stabilization. It offers high vibration rejection, a wide temperature range, and a built‑in temperature sensor.
The document provides detailed specifications, absolute maximum ratings, pin configuration, theory of operation, bandwidth setting, and typical performance characteristics, along with self‑test procedures and supply requirements.
