ADXRS645HDYZ

The ADXRS645HDYZ is a high-performance Angular Rate Sensor with excellent vibration immunity for use in high temperature environments. It is manufactured using the Analogue Devices, Inc., patented high volume BiMOS surface-micromachining process with years of proven field reliability. An advanced, differential, quad sensor design provides superior acceleration and vibration rejection. The output signal, RATEOUT, is a voltage proportional to the angular rate about the axis normal to the package lid. The measurement range is a minimum of ±2000°/second and may be extended to ±5000°/second with the addition of a single external resistor. The output is ratiometric with respect to a provided reference supply. Other external capacitors are required for operation. A temperature output is provided for compensation techniques. Two digital self-test inputs electromechanically excite the sensor to test proper operation of both the sensor and the signal conditioning circuits.
