GENERAL DESCRIPTION
The ADXRS613 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 output signal, RATEOUT (1B, 2A), is a voltage proportional
to the angular rate about the axis that is normal to the top sur-
face of the package. The output is ratiometric with respect to a
provided reference supply. A single external resistor between
SUMJ and RATEOUT 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 ADXRS613 is available in a 7 mm ×
7 mm × 3 mm BGA chip scale package.
