The ADXRS64x family of low noise, vibration rejecting yaw rate gyroscopes are drop-in performance upgrades to existing designs using the ADXRS62x family.
The ADXRS642BBGZ-RL 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 ADXRS642BBGZ-RL 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 ADXRS642BBGZ-RL 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 proportionalto 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 ADXRS642BBGZ-RL is available in a 7 mm × 7 mm × 3 mm BGA chip-scale package.
