TI中文支持网Part Number:ADC16DV160HFEBOther Parts Discussed in Thread:WAVEVISION5, ADC16DV160,
Hello, two weeks ago I was able to use this board normally, but now when I open the WaveVision5 software, an error message pops up. Even though I followed its instructions, the error persists, and I could use it just fine two weeks ago. Additionally, when powering the ADC16DV160, it heats up excessively, and a 3V input voltage corresponds to a current of around 4A. I would really appreciate your help. Thank you.

您好，
如果供电时ADC16DV160HFEB板子发烫，存在过流情况，请检查板子是否存在短路情况。

Hello, thank you for your reply. The power sequence of the board is correct, and the data capture board is recognized in the device manager on the computer. However, the issue of excessive current and severe overheating still exists. I believe this might be the main reason why it is not functioning properly. If I want to check whether the board is short-circuited, what specific steps should I take?

You're very welcome. I am currently checking the issues with this board. Could you tell me what the expected current values are for each of the four input voltages when the board is operating normally?

Hello, after inspection, there are no issues with the surrounding circuitry, so it seems that the main control chip is likely damaged. Do you think this board is still worth repairing? If I were to proceed with the repair, where should I take it?
