High Stability, Low Noise Vibration Rejecting Yaw Rate Gyroscope Enhanced Product ADXRS646-EP FEATURES GENERAL DESCRIPTION 12/hr bias stability The ADXRS646-EP is a high performance angular rate sensor Z-axis (yaw rate) response (gyroscope) that offers excellent vibration immunity. Bias stability 0.01/sec angle random walk is a widely recognized figure of merit for high performance gyro- High vibration rejection over wide frequency scopes, but in real-world applications, vibration sensitivity is Measurement range extendable to a maximum of 450/sec often a more significant performance limitation and should be 10,000 g powered shock survivability considered in gyroscope selection. The ADXRS646-EP offers Ratiometric to referenced supply superior vibration immunity and acceleration rejection as well 6 V single-supply operation as a low bias drift of 12/hr (typical), enabling it to offer rate sens- Self-test on digital command ing in harsh environments where shock and vibration are present. Ultrasmall and light (<0.15 cc, <0.5 gram) The ADXRS646-EP is manufactured using the Analog Devices, Temperature sensor output Inc., patented high volume BiMOS surface-micromachining Complete rate gyroscope on a single chip process. An advanced, differential, quad sensor design provides RoHS compliant the improved acceleration and vibration rejection. The output ENHANCED PRODUCT FEATURES signal, RATEOUT, is a voltage proportional to angular rate about Supports defense and aerospace applications the axis normal to the top surface of the package. The measure- Extended industrial temperature range (55C to +105C) ment range is a minimum of 250/sec. The output is ratiometric Controlled manufacturing baseline with respect to a provided reference supply.
