The ADXRS620BBGZ-RL is a complete angular rate sensor (gyroscope)that uses the Analog Devices, Inc. surface-micromachiningprocess to create a functionally complete and low cost angularrate sensor integrated with all required electronics on one chip.The manufacturing technique for this device is the same highvolume BiMOS process used for high reliability automotiveairbag accelerometers.
The ADXRS620BBGZ-RL is an automotive grade gyroscope that has 100% pin, package, temperature, and function compatible to the available industrial grade ADXRS652 gyro. Automotive grade gyroscopes have more extensive guaranteed min/max specifications due to automotive testing.
The output signal, RATEOUT (1B, 2A), is a voltageproportional to angular rate about the axis normal to the topsurface of the package. The output is ratiometric with respect toa provided reference supply. A single external resistor can beused to lower the scale factor. An external capacitor sets thebandwidth. Other external capacitors are required for operation.
A temperature output is provided for compensation techniques.Two digital self-test inputs electromechanically excite thesensor to test proper operation of both the sensor and the signalconditioning circuits. The ADXRS620BBGZ-RL is available in a 7 mm ×7 mm × 3 mm BGA ceramic package.
