The ADXRS64x family of low noise, vibration rejecting yaw rate gyroscopes are drop-in performance upgrades to existing designs using the ADXRS62x family.
The ADXRS642 is a drop-in performance upgrade to existing designs of the ADXRS62x family and is rated at ±250°/s bringing improved vibration and shock immunity performance.
The ADXRS642 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc., 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 a patented high volume BiMOS process with years of proven field reliability.
The ADXRS642 is an industrial grade gyroscope that is 100% pin, package, temperature, and function compatible with the ADXRS622 and ADXRS652 – while offering enhanced vibration rejection.
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 measurement range is a minimum of ±250°/s. The output is ratiometric with respect to a provided reference supply. 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 conditioning circuits. The ADXRS642 is available in a 7 mm × 7 mm × 3 mm BGA chip-scale package.
- Industrial applications
- Inertial Measurement Units
- Severe Mechanical Environments

Evaluation Kits (1)
The EVAL-ADXL642Z is a simple breakout board that allows quick evaluation of the performance of the ADXRS642 angular-rate sensor (gyroscope). The ADXRS642 is a high performance analog-output gyroscope featuring yaw-rate sensing and excellent immunity to vibration and linear acceleration. The small size of the breakout board makes it easy to mount the gyroscope to an existing system without the need for additional hardware and with minimal effect on performance of the system and of the gyroscope. The board comes populated with all required passives, as specified in the User Guide below.
This page contains all the information related to the EVAL-ADXRS642Z including documentation, pricing, and ordering information.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.
