±300°/sec Yaw Rate Gyro ADXRS620 FEATURES GENERAL DESCRIPTION Qualified for automotive applications
The ADXRS620 is a complete angular rate sensor (gyroscope)
Complete rate gyroscope on a single chip
that uses the Analog Devices, Inc., surface-micromachining
Z-axis (yaw rate) response
process to create a functionally complete and low cost angular
High vibration rejection over wide frequency
rate sensor integrated with all required electronics on one chip.
2000 g powered shock survivability
The manufacturing technique for this device is the same high
Ratiometric to referenced supply
volume BiMOS process that is used for high reliability automotive
5 V single-supply operation
airbag accelerometers.
105°C operation Self-test on digital command
The ADXRS620 is an automotive grade gyroscope that is 100%
Ultrasmall and light (<0.15 cc, <0.5 gram)
pin, package, temperature, and function compatible to the
Temperature sensor output
available industrial grade ADXRS652 gyro. Automotive grade
RoHS compliant
gyroscopes have more extensive guaranteed minimum/maximum
APPLICATIONS
specifications due to automotive testing.
Vehicle chassis rollover sensing
The output signal, RATEOUT (1B, 2A), is a voltage that is
Inertial measurement units
proportional to angular rate about the axis normal to the top
Platform stabilization
surface of the package. The output is ratiometric with respect to a provided reference supply. 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 condi- tioning circuits. The ADXRS620 is available in a 7 mm × 7 mm × 3 mm BGA ceramic package.
