The ADXRS646 is a high performance angular rate sensor (gyroscope) that offers excellent vibration immunity. Bias stability is a widely-recognized figure of merit for high performance gyroscopes, but in real-world applications, vibration sensitivity is often a more significant performance limitation and should be considered in gyroscope selection. The ADXRS646 offers superior vibration immunity and acceleration rejection as well as a low bias drift of 12°/hr (typical), enabling it to offer rate sensing in harsh environments where shock and vibration are present.

The ADXRS646 is manufactured using the Analog Devices, Inc., patented high volume BiMOS surface-micromachining process. An advanced, differential, quad sensor design provides the improved acceleration and vibration rejection. The output signal, RATEOUT, 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°/sec. 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 ADXRS646 is available in a 7 mm × 7 mm × 3 mm CBGA chip-scale package.

Product Details

The EVAL-ADXRS646Z is a simple breakout board that allows quick evaluation of the performance of the ADXRS646 angular-rate sensor (gyroscope). The ADXRS646 is a very high performance analog-output yaw-rate gyroscope featuring low bias drift of 12°/hr 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-ADXRS646Z including documentation, pricing, and ordering information.
