GENERAL DESCRIPTION
The ADXRS300 is a complete angular rate sensor (gyroscope)
that uses Analog Devices’ 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 angular rate about the axis normal to the top surface of the
package (see Figure 4). A single external resistor can be used to
lower the scale factor. An external capacitor is used to set the
bandwidth. Other external capacitors are required for operation
(see Figure 5).
A precision reference and a temperature output are also
provided for compensation techniques. Two digital self-test
inputs electromechanically excite the sensor to test proper
operation of both sensors and the signal conditioning circuits.
The ADXRS300 is available in a 7 mm × 7 mm × 3 mm BGA
chip-scale package.
