[SOLVED] PIC32 Microcontroller getting heated up when input is given to comparator

[freemanantony]

Hai everybody,
i am using pic32 microcontroller. For testing comparator module i have given 1.8V to the C1IN+ pin which is configured to be connected to comparator inverting input and CVref(1.55V) is configured to be connected to non-inverting input of comparator. When i have given 1.8V input the controller is getting heated up and i fear thus i damaged the controller. Has anyone experienced the same problem and can anyone help me to avoid this problem.

Post your schematic..

Check supply & Ground connections..

Difficult to help without a schematic but the usual cause is the comparator input is shared with another peripheral and you have it configured as an output.
