Hi,
I made a design using the DIT4096 and I have trouble with the power supply
I have one LDO whom provides 5V on VBUS
and another LDO whom uses the 5V to prodive 3,3V on VDDAM
To do my test I started by not soldered R49 so I power only the pin19 VDD (the Digital Core Power-Supply) at +5V
And I have the surprise to have 4,3V on the pin 7 call in the datasheet Vio (Digital I/O Power Supply, +2.7V to VDD)
And of course if I solder R49 to connect Vio to VDDAM my 3,3V is affected and I have 4,3V on VDDAM.
I don't understand does I have a broken DIT4096?
Do you see something wrong with my schematic?
Thanks in advance for your help
