GENERAL DESCRIPTION
The ADXRS150 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 the angular rate about the axis normal to the top surface of
the package (see Figure 2). 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 22).
A precision reference and a temperature output are also pro-
vided for compensation techniques. Two digital self-test inputs
electromechanically excite the sensor to test the operation of
both sensors and the signal conditioning circuits. The ADXRS150
is available in a 7 mm × 7 mm × 3 mm BGA surface-mount
package.
