Kit Overview

The Analog Devices EVAL-ADXRS646ZEVAL-ADXRS646Z is a simple evaluation board that allows quick evaluation of the performance of the ADXRS646 ±250°/sec yaw rate gyroscope. No additional external compo-nents are required for operation. The EVAL-ADXRS646Z has a 20-lead, dual in-line (0.3 inch width × 0.1 inch pin spacing) interface that allows easy prototyping of products without BGA soldering.

The ADXRS646ADXRS646 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 ADXRS646ADXRS646 is pin - and package - compatible to the ADXRS62x family and offers a measurement range of ±250°/s, 1 kHz bandwidth, 12°/hr drift with low broadband noise, low g sensitivity of 0.015°/s/g and vibration rectification of 0.0001°/s/g², is ideally suited for high performance navigation and platform stabilization.

The ADXRS646ADXRS646 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 and vibration, enabling the ADXRS646 to offer rate sensing in harsh environments where shock and vibration are present.
