The EVAL-ADXRS622 is a simple evaluation board that allows quick evaluation of the performance of the ADXRS622 ±250°/sec yaw rate gyro. No additional external components are required for operation, the analog supply voltage and charge pump supply voltage (AVCC and VDD) are not connected on the EVAL-ADXRS622. The ADXRS622 is a complete angular rate sensor (gyroscope) that uses the ADI's, 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 the same high volume BiMOS process used for high reliability automotive airbag accelerometers. 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.
