The ADXRS620 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc. surface-micromachining process to create a functionally complete and low cost angular rate sensor integrated with all 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 ADXRS620 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 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. A single external resistor can be used to lower the scale factor. An external capacitor sets 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 ADXRS620 is available in a 7 mm × 7 mm × 3 mm BGA ceramic package.
- Vehicle chassis rollover sensing
- Inertial measurement units
- Platform stabilization
