Hi,
Our customer is using AM335x TSC ADC to measure analog signals,
but the ADC results are uncertain.
The measured ADC voltage value is greater than the input voltage value.
With some testing came to know the voltage at the ADC input pin increases
at the moment when the ADC is enabled.
Also tried to increase the Open delay, but increasing the Open delay also
increases the duration of the increased input voltage.
And also, when the ADC port is enabled, there seems be reverse current flowing
out from the ADC port to the external circuit.
Please let us know if there is any suggestion to solve this issue.
Regards.
