THS4211, input attenuator introduces offset voltage at the output.

Other Parts Discussed in Thread: THS4211

Hello ti community,

I've been having a problem with THS4211 current feedback opamp. The problem is when I add X10 attenuator with input resistance of 100k the output is the shifted version of the input signal, it has DC offset at the output and it's not a really tiny offset. I shared some pictures and the files too please check them out. The output has -70mV offset and the intermediate node at the input has -35mV offset. current_feedback_input_attenuator.TSC
