Hi, I'm having a lot of noise from my external ADC, and I suspect it's the fault of the board.
The ADC is 10MHz, and 12-bit, and I'm getting around 4-bits of noise, equivalent to 7mV on it. Lower clock frequencies have no effect on it.
Can someone please take a quick look at my PCB / schematic and see if there's anything obviously wrong with it?

Any help would be greatly appreciated!
