The ADXRS623BBGZ-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 ADXRS623BBGZ-RL is an automotive grade gyroscope. Automotive grade gyroscopes have more extensive guaranteed min/max specifications due to automotive testing.
The output signal, RATEOUT (1B, 2A), is a voltageproportional to the angular rate about the axis that is normal tothe top surface of the package. The output is ratiometric withrespect to a provided reference supply. A single externalresistor between SUMJ and RATEOUT can be used to lowerthe scale factor. An external capacitor sets the bandwidth. Otherexternal 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 ADXRS623BBGZ-RL is available in a 7 mm ×7 mm × 3 mm BGA chip scale package.
