When this problem is the question to be sent to the board design maker, I understand.
But because the answer can not be obtained, I will question here.
Chip is "ADS7816".
There are analog input circuit of 0-10V that has been designed in this chip.
My question. The operation for the input signal at a frequency 50Hz to the input circuit.
Signal swings to ± both side. Voltage width is at least 2V.
This chip is frozen?
It is, of course, the wrong signal is in on the know.
