±300°/sec Yaw Rate Gyro
ADXRS620
GENERAL DESCRIPTION
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 that is used for high reliability automotive
airbag accelerometers.
The output signal, RATEOUT (1B, 2A), is a voltage that is
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. 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 condi-
tioning circuits. The ADXRS620 is available in a 7 mm × 7 mm ×
3 mm BGA ceramic package.
