GENERAL DESCRIPTION
The ADXRS652 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 a patented
high volume BiMOS process with years of proven field
reliability.
The output signal, RATEOUT (1B, 2A), is a voltage propor-
tional 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 is used to set
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 ADXRS652 is available in a 7 mm × 7 mm ×
3 mm BGA chip-scale package.
