negative adc with pic
will it be ok to to allow more then +/-5 volt to appear on the Port A of PIC series microcontroller
or i should scale down the voltages before reading them
i am keeping in the mind that there is built in diode protection for negative voltages and the more then 5 volt positive voltages
thats why i have not included external diode to clip the negative side voltage
but wanna learn will it be ok not to use the external diode and to keep faith in the built in diode for the protection of ADC
