Arduino DUE - DAC0 problems

Hello

I'm trying the dac of arduino DUE. The channel DAC1 working good, i set a value with analogWrite() ,and i measure him in output. (4095 = 2.75V)

The dac0 instead has problems suddenly.

I measure the voltage set properly in the software, but does not deliver current..then when i connect something, the voltage drops down.

Say that I burned the pin ?

Sorry for my english !!

Thank you

Yes, sounds like a burned-out pin.

They are easy to damage.

I can do some checking ? I can solve it ?
