±150°/Sec Yaw Rate Gyroscope ADXRS623 FEATURES GENERAL DESCRIPTION Complete rate gyroscope on a single chip
The ADXRS623 is a complete angular rate sensor (gyroscope)
Z-axis (yaw rate) response
that uses the Analog Devices, Inc., surface-micromachining
High vibration rejection over wide frequency
process to create a functionally complete and low cost angular
2000 g powered shock survivability
rate sensor integrated with all required electronics on one chip.
Ratiometric to referenced supply
The manufacturing technique for this device is the same high
5 V single-supply operation
volume BiMOS process used for high reliability automotive
–40°C to +105°C operation
airbag accelerometers.
Self-test on digital command Ultrasmall and light (<0.15 cc, <0.5 gram)
The output signal, RATEOUT (1B, 2A), is a voltage proportional
Temperature sensor output
to the angular rate about the axis that is normal to the top surface
RoHS compliant
of the package. The output is ratiometric with respect to a pro-
Qualified for automotive applications
vided reference supply. An external capacitor sets the bandwidth.
APPLICATIONS
Other external capacitors are required for operation.
Inertial measurement units
A temperature output is provided for compensation techniques.
Platform stabilization
Two digital self-test inputs electromechanical y excite the sensor to
Robotics
test proper operation of both the sensor and the signal conditioning circuits. The ADXRS623 is available in a 7 mm × 7 mm × 3 mm ceramic bal grid array (CBGA) package.
