[PIC] Maximum input current to PIC18f4520

[KhaledOsmani]

Hello,

What is the maximum permissible current enabled to enter to analogue pins of PIC18f4520 with no damage over PIC's functioning?

Assuming a load of 0.3 A, I want to branch in series a current transformer, to be able entering the PIC porta pins.

Can this connection be directly branched without any requirements of extra components (such as current limiters, etc...)?

Voltage speaking, to enter a max allowable voltage of 5V to PIC analogue pin, risky margins should be taken into consideration, and a small capacitor (of 10nF) must be parallelly connected before entering the PIC.

Does some restrictions also must be taken into consideration when entering current? Any datasheet name for a standard current transformer for PIC MCU?

If extra information about connection methodology must be done, please provide

thanks

If you want to measure maqins current then use hall sensor like this

What C.T are you using. Provide its datasheet. Are you using OpAmps between C.T. and PIC ADC input ?
