I have a question about power supply of ADXL355.
Should we separately drive to Vsupply and VDDIO from different LDO?
The application engineer for this product is on vacation this week, but I think that we can help with this one. I would think that you would have much better visibility in the trade-offs associated with your application than we would. If I am not mistaken, the purpose of separating these supplies is to give you the option to interface with a processor, whose I/O voltages are different than the supply for the sensor. This is different than separating the analog and digital supplies on an A/D converter, where managing the signal fidelity against EMI and other noise coupling is the primary drive.
Anthony.DeSimone: When you get back, can you double check my answer on this one?
