I am attempting to build something similar to what is detailed in Application Report SLAA545, with the same hardware, which I currently have.
The main difference is that I need the analog inputs and outputs to be DC coupled.
Starting with the ADS4249EVM.. the table below from the user’s guide indicates rewiring needed to use the opamp for driving the input. I can find these resistors and locationson the board by searching the assembly drawing, but removing and adding new resistors to this board seems like an impossible task. Any hints on how I can do that? Or better yet, if I can order a new board with all of this already done.
The same question goes for the DAC3482EVM. From the schematic below, it looks like I need to remove T2 and T3 and in 0 Ohm resistors for R20, R24, R25, R28, R32, and R34. Is this correct? That looks slightly easier to do than modifying the ADS4249EVM board, but still pretty tough.
Thank you. My next questions will be about power supplies and clocks.
