The ADXRS646TBGZ-EP is a high performance angular rate sensor(gyroscope) that offers excellent vibration immunity. Biasstability is a widely-recognized figure of merit for highperformance gyroscopes, but in real-world applications,vibration sensitivity is often a more significant performancelimitation and should be considered in gyroscope selection. TheADXRS646TBGZ-EP offers superior vibration immunity and accelerationrejection as well as a low bias drift of 12°/hr (typical), enabling itto offer rate sensing in harsh environments where shock andvibration are present.
The ADXRS646TBGZ-EP is manufactured using the Analog Devices,Inc., patented high volume BiMOS surface-micromachiningprocess. An advanced, differential, quad sensor design providesthe improved acceleration and vibration rejection. The outputsignal, RATEOUT, is a voltage proportional to angular rateabout the axis normal to the top surface of the package. Themeasurement range is a minimum of ±250°/sec. The output isratiometric with respect to a provided reference supply. Otherexternal capacitors are required for operation.
A temperature output is provided for compensation techniques.Two digital self-test inputs electromechanically excite the sensorto test proper operation of both the sensor and the signal conditioningcircuits.
The ADXRS646TBGZ-EP is available in a 7 mm × 7 mm × 3 mm CBGAchip-scale package.
