ADP5020ACPZ，在无任何负载器件下，输入电压7V时，电流0.22A，不知道问题出在哪里

So ideally don't you want the S parameters of the ADC front end to match the balun optimially? asked by Steven N.

Don't you need a centertap balun so meet the common mode bias requirements of the ADC? Or else you need to deal with capactively coupling of the inputs which can also result in imbalance. asked by Steven N.

Which double balun configuration have you found to be best? asked by Scott T.

1:1 Baluns covering wide frequencies seem widely available. However, 1:2 Baluns seem to be narrower and less available. Why is this? asked by Robert B.

Why put a higher BW then "necessary" inside the ADC IC? asked by Nan Z.

Given the dynamic nature of an ADC's input impedance (due to switching), how practical is it to employ classic RF matching techniques (tuning out L/C)? asked by Josh H.

Are there recommended references for PCB stackup and using special PCB materials other than FR4 such as Nelco-SI? Possibly, thermal issues? asked by Don G.
