Dear Sir or Madam
If only the DVCC of AD5560 be supplied by 3.3V , refer to DGND . Can I access the all the registers ?
For there is a phenomenon , sometimes , if I disable the negative power rail which supplies AVss , HCAVss of AD5560 . The registers we read will be all 0x0000 , as opposed to the case which the negative power is enabled .
Thank you in advance for your tips about above .
We can only guarantee a successful access on all the registers if you have the AVdd and AVss still connected. If you're trying to conserve power, you just need to have the AD5560 in Power Down mode.
Let me know if this makes sense to you.
