ADXRS620 ±300°/sec Yaw Rate Gyro
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.
