Forum Post: RE: TMUX4052: TMUX4052 application on ADC sampling
Hello Shaohui, 1. What 120ohm are you referring to? I am assuming you are looking at the VDD = 24V case. The Ron goes from mux of 120ohms at 25C to 150ohms at 85C. Also, what measurements did you get?...

Hi Erin, But I think in the case of the sinewave, we can't adjust the peak to peak voltage when using external gain because to adjust peak to peak we can only play with the gain. Even if with margin...
