Arijit Banerjee

Part Number: TMS570LS3137

Tool/software:

Does the microcontroller TMS5703137CGWTQEP have any internal protection circuit on the ADC input lines to prevent damage due to high voltage?

Hi Arijit,

Yes, there will be a clamping circuit to protect the inputs from high voltages.

The absolute maximum voltage that can be applied to the ADC input pin is 6.25v.

You can refer below thread to understand more details about this.
