I am sorry that we have not responded to this yet. Based on my understanding of this device, your experience is appropriate. I have not read the ADIS16460 datasheet is a while but I do know that the next generation devices (ADIS16465, ADIS16467) are not able to support 32-bit reads at the maximum ODR, so I suspect that the same limitation exists in the ADIS16460 (even if not documented). I will check into the documentation (need to update?) but is this a requirement for you? Assuming you are not using the internal filters, 16-bits will provide sufficient resolution for preserving full performance in the gyroscopes and sensors. Thank you for your post and follow up! Really sorry that this was missed.
