GENERAL DESCRIPTION
The ADXRS622 is a complete angular rate sensor (gyroscope)
that uses the Analog Devices, Inc., surface-micromachining
process to make a functionally complete and low cost angular
rate sensor integrated with all of the 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 output signal, RATEOUT (1B, 2A), is a voltage proportional to
the angular rate about the axis that is 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 ADXRS622 is available in a 7 mm × 7 mm ×
3 mm BGA chip-scale package.
