Datasheet
ADXRS649 on Analog.com
ADXRS649 Datasheet specifies all data at VS = AVCC = VDD = VRATIO = 5 V. In my system, a 0-3.3 V output is beneficial. I am currently using the eval board with external voltage dividers for the gyro and the temp output to scale them down, which works ok. I wonder if I can omit the external dividers and directly supply VRATIO with 3.3 V? Thus, VS = AVCC = VDD = 5 V while VRATIO = 3.3 V. Is this a supported mode of operation?
Hi JanLo
Thank you for your request on this. I am not sure that we characterized this option but let me check. Just FYI, I am the back-up of the back-up for this product, so it might take a bit of time to conduct this research. Thanks again!
