May I ask a question about output data rate for ADIS16080 ? Because datasheet has no description.
But some Gyro MEMS datasheets describe Output Data Rate(ODR) parameter.
The SPI CS & SCLK signals control the sampling. The ODR is only useful for devices that have internal clocks, which have fixed sample rates. I hope that makes sense. If not, we look forward to your next question.
Excuse me, I want to ask another question: As I know, ADI's all Gyros specification have no Output Data Rate(ODR), that means all Gyros have no internal clock. But why some vendor (example: 1-Axis Gyro ISZ-2510 of Invenssense) many Gyros need internal clock ? I do not understand.
Gyroscopes are transducers, which translate rotation rate into electrical signals. That's it. For those that want those signals to be in some sort of digital format, they needed analog-to-digital converter o'clock to drive it. In the case of our product, which you are investigating through this discussion, the analog-to-digital converter provides you, the user, with the flexibility of providing the clock rate that you desire.
MEMS Technology has generated a bunch of different gyroscopes, which come with a bunch of different interface options. While some offer convenience advantages, by including all functions necessary to produce digital data, others may present better performance under certain conditions.
It sounds like you're on the right track, but I would encourage you resist defining such a broad term in such a narrow way.
What type of project are you working on?
Thanks for your reply and information.
We want to develop a measurement tool that can measure Caster/KingPin angle for Car's alignment.
In measurement process, we need user turn the wheel to left 20 degree then turn wheel to right 40 degree, and Car is not running. We hope make a measurement tool to instead of Turn table.

Looks like a very interesting application. Thank you for sharing this!
