±300°/sec Yaw Rate Gyro ADXRS620 Qualified for automotive applications 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 105°C operation Self-test on digital command Ultrasmall and light cc, gram Temperature sensor output RoHS compliant Vehicle chassis rollover sensing Inertial measurement units Platform stabilization The ADXRS620 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 that is used for high reliability automotive airbag accelerometers. The ADXRS620 is an automotive grade gyroscope that is 100% pin, package, temperature, and function compatible to the available industrial grade ADXRS652 gyro. Automotive grade gyroscopes have more extensive guaranteed minimum/maximum specifications due to automotive testing. The output signal, RATEOUT 1B, 2A , is a voltage that is 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. 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 conditioning circuits. The ADXRS620 is available in a 7 mm x 7 mm x 3 mm BGA ceramic package.
