ADXRS649Fast Starting, ±20,000°/sec Vibration Rejecting Rate Gyro | Development Boards, Kits, Programmers | 3 | Active | The ADXRS64x family of low noise, vibration rejecting yaw rate gyroscopes are drop-in performance upgrades to existing designs using the ADXRS62x family.The ADXRS649 is pin- and package-compatible to the ADXRS62x family and offers the highest rate of rotation sensing available with ±20,000°/sec and fast 3 millisecond (ms) startup for quick power cycling. This measurement range is extendable to ±50,000°/sec with the addition of an external resistor. It is ideally suited for applications where exceptionally wide measurement ranges are needed.The ADXRS649 is a complete angular rate sensor (gyroscope) that uses the Analog Devices, Inc., patented high volume BiMOS surface-micromachining process to make a complete gyro on one chip. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS649 to offer rate sensing in harsh environments where shock and vibration are present.The output signal, RATEOUT (B1, A2), is a voltage proportional to the 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 is used to set the band-width. The measurement range is extendable to ±50,000°/sec by adding an external resistor.Low power consumption (3.5 mA) enables very low power consumption, and ultrafast startup (3 ms) allows for quick power cycling of the gyro. At 10 samples per second, a pair of CR2032 coin cells can power the ADXRS649 for three months.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 condi-tioning circuits. The ADXRS649 is available in a 7 mm × 7 mm × 3 mm CBGA chip scale package.ApplicationsSports equipmentIndustrial applicationsForm stabilizationHigh speed tachometry |

ADXRS910Rollover Detection In-Plane Gyroscope | Gyroscopes | 1 | Active | The ADXRS910 is a high performance in-plane gyroscope, designed for automotive rollover detection applications. The ADXRS910 also has an internal temperature sensor that is used to compensate offset and sensitivity performance, providing excellent stability over the −40°C to +105°C temperature range.The gyroscope provides a full-scale range of ±300°/sec with a sensitivity of 80 LSB/°/sec. Its resonating disk sensor structure enables angular rate measurement around an in-plane axis. The −3 dB filter corner frequency can be selected to be 27.6 Hz, 51.3 Hz, 109 Hz, or 196.8 Hz. The sensor data output from the device is a 16-bit, twos complement word contained in a 32-bit SPI transaction. SPI communications are compatible up to 10 MHz.The ADXRS910 is available in a 16-lead inverted SOIC package. The ADXRS910 is specified to operate at 3.3 V and 5 V, with less than 20 mA of current consumption. Its specifications are valid over the −40°C to +105°C temperature range.ApplicationsRollover detection |
