ADI ADXRS622: ±250°/sec Yaw Rate Gyroscope


What is it?
The ADXRS622 is the successor of the ADXRS612. The ADXRS622 is pin compatible and has the same electrical characteristics as the ADXRS612 but has a capped sensor as protection against particles and to further increase quality levels. The ADXRS622 is a complete angular rate sensor (gyroscope) that uses Analog Devices' 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. The output signal, RATEOUT, is a voltage proportional to angular rate about the axis normal to the top surface of the package. The output is ratio metric with respect to a provided reference supply. A single external resistor can be used to lower the scale factor. 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 ADXRS622 is available in a 7 mm × 7 mm × 3 mm BGA chip-scale package.

How is it used?
The ADXRS622 is primarily intended for use in automotive rollover applications; however, this product may also be of interest in consumer, industrial and military/aerospace applications such as inertial measurement units and platform stabilization.
