Fast Starting, ±20,000°/sec Vibration Rejecting Rate Gyro

Product Details

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.

Product Details

The EVAL-ADXL649Z is a simple breakout board that allows quick evaluation of the performance of the ADXRS649 angular-rate sensor (gyroscope). The ADXRS649 is a high performance analog-output yaw-rate gyroscope with ±20,000°/sec measurement range (extendable to ±50000°/s), and featuring 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-ADXRS649Z including documentation, pricing, and ordering information.
