Yes, you can go above 100ohms. Though the filter flatness may be more difficult to achieve and the ADCdynamic performance may not be as good.

Gauraw,
An ADS2014 project using an unencrypted THS770012 model is attached to this thread,
The original unencrypted Pspice netlist is in the project working directory.
Please let me know if you have any questions.

Hi Naveen P,
Thank you for sharing the schematics. In order to further assist, can you please share the layout that would include the inputs/output for the ADCs including to the FPGA?
Here are some questions from schematic review:
The VRN and VRP…
Other Parts Discussed in Thread: THS4520 , THS4130 , THS770012 Hi,
we are using the TSH4520 to generate a differential output with CM=0.75V.
the differential output range is from 0 to 1.5Vpp. That means the THS4520 differential outputs will be…
