i want to connect it with arduino but arduino has i2c network for communication. it is not mentioned in data sheet which communication protocol follow for adxrs649.
Thank you for your post and for your interest in the ADXRS649. This gyroscope does not have a serial data interface. It has an analog output, which you will need to connect to a ratio-metric ADC interface. I am not familiar enough with the Arduino to offer a specific recommendation, but I suspect that such an interface would be available in one of those platforms.
