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.

SPECIFICATIONS @TA = 25°C, VS = 5 V, bandwidth = 80 Hz (COUT = 0.01 µF), angular rate = 0°/s, ±1g, unless otherwise noted.
Table 1. All min and max specifications are guaranteed. Typical specifications are not tested or guaranteed.
2 Dynamic range is the maximum full-scale measurement range possible, including output swing range, initial offset, sensitivity, offset drift, and sensitivity drift at
5 V supplies.
3 Specification refers to the maximum extent of this parameter as a worst-case value at TMIN or TMAX.
ABSOLUTE MAXIMUM RATINGS
Table 2. Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at these or any
other conditions above those indicated in the operational sec-
tion of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Applications requiring more than 200 cycles to MIL-STD-883
Method 1010 Condition B (–55°C to +125°C) require underfill
or other means to achieve this requirement.
Drops onto hard surfaces can cause shocks of greater than
2000 g and exceed the absolute maximum rating of the device.
Care should be exercised in handling to avoid damage.
RATE SENSITIVE AXIS This is a Z-axis rate-sensing device that is also called a yaw rate
sensing device. It produces a positive going output voltage for
clockwise rotation about the axis normal to the package top, i.e.,
clockwise when looking down at the package lid.
Figure 2. RATEOUT Signal Increases with Clockwise Rotation
ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
