GENERAL DESCRIPTION
T
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 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 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 ADXRS624 is available in a 7 mm ×
7 mm × 3 mm BGA chip scale package.
he ADXRS624 is a complete angular rate sensor (gyroscope)
