OPA333: ECG TINA simulation

As showed, R is set 140k which is connected to Rs5, and the AC Transfer characteristc results is showed below: 

But when we sweep this R, the result at 140k(red line) is different with the first simulation result.

您可以附上您的仿真文件吗？

第一个曲线图中有3条曲线，您指的是哪条曲线？您说的是VoRLD输出与输入VG1的传输特性曲线吗？
