EVAL-ADXRS652Z

The ADXRS652 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc. surface-micromachining process to make a functionally complete and low cost angular rate sensor integrated with all of the required electronics on one chip. The manufacturing technique for this device is a patented high volume BIMOS process with years of proven field reliability. The ADXRS652 is an industrial grade gyroscope that 100% pin, package, temperature, and function compatible to the related automotive grade ADXRS620 and ADXRS622 gyroscopes. Automotive grade gyroscopes have more guaranteed min/max specifications due to automotive testing. The output signal, RATEOUT (1B, 2A), is a voltage proportional to angular rate about the axis normal to the top surface of the package. The output is ratiometric with respect to a provided reference supply. An external capacitor is used to set the bandwidth. 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. The ADXRS652 is available in a 7 mm × 7 mm × 3 mm BGA chip-scale package.
