FEATURES  
GENERAL DESCRIPTION  
Complete rate gyroscope on a single chip  
Z-axis (yaw rate) response  
High vibration rejection over wide frequency  
2000 g powered shock survivability  
Ratiometric to referenced supply  
5 V single-supply operation  
The ADXRS614 is a complete angular rate sensor (gyroscope)  
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.  
105°C operation  
Self-test on digital command  
Ultrasmall and light (<0.15 cc, <0.5 gram)  
Temperature sensor output  
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.  
RoHS compliant  
APPLICATIONS  
Navigation systems  
Inertial measurement units  
Platform stabilization  
Robotics  
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 ADXRS614 is available in a 7 mm ×  
7 mm × 3 mm BGA chip scale package.
