I'm so glad to your support!
At present,I am evaluating AD2S1210 with attached schematic.When I configurate AD2S1210,Vdriver will 3.3V up to 3.7V.Vdd=5V,AVDD=5V.
Could you give some comments about why the Vdiver will up to 3.7V?many thanks!
Looking at the schematic there is nothing obvious that would indicate why 3.7V would be present on the Vdrive supply.
Some points to check would be
- is the logic levels on the signals that controlled by you uC also set to 3.3V
- have you ruled out any shorts on the board
- if you can isolated your power supplies or RDC from the uC turn them on individually to narrow down which one is having the effect on Vdrive.
