Analog Devices ADXRS646-EP Yaw Rate Gyroscope

Analog Devices ADXRS646-EP Yaw Rate Gyroscope

Analog Devices ADXRS646-EP High Stability, Low Noise Vibration Rejecting Yaw Rate Gyroscope is a high performance angular rate sensor that offers excellent vibration immunity. Bias stability is a widely recognized figure of merit for high performance gyroscopes, but in real-world applications, vibration sensitivity is often a more significant performance limitation and should be considered in gyroscope selection. ADI ADXRS646-EP offers superior vibration immunity and acceleration rejection as well as a low bias drift of 12°/hr (typical), enabling it to offer rate sensing in harsh environments where shock and vibration are present. An advanced, differential, quad sensor design provides the improved acceleration and vibration rejection. The output signal, RATEOUT, is a voltage proportional to angular rate about the axis normal to the top surface of the package. The measurement range is a minimum of ±250°/sec. The output is ratiometric with respect to a provided reference supply. Other external capacitors are required for operation.
