ADXRS646

Data Sheet High Stability, Low Noise Vibration Rejecting Yaw Rate Gyroscope ADXRS646 FEATURES GENERAL DESCRIPTION 12°/hr bias stability Z-axis (yaw rate) response 0.01°/√sec angle random walk High vibration rejection over wide frequency Measurement range extendable to a maximum of ±450°/sec 10,000 g powered shock survivability Ratiometric to referenced supply 6 V single-supply operation −40°C to +105°C operation Self-test on digital command Ultrasmall and light (<0.15 cc, <0.5 gram) Temperature sensor output Complete rate gyroscope on a single chip RoHS compliant APPLICATIONS Industrial applications Severe mechanical environments Platform stabilization The ADXRS646 is a high performance angular rate sensor (gyroscope) 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. The ADXRS646 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. The ADXRS646 is manufactured using the Analog Devices, Inc., patented high volume BiMOS surface-micromachining process. An advanced, differential, quad sensor design provides the improved acceleration and vibration rejection. The output signal, RATEOUT, is a voltag...
