Hi all,
I am looking to do some A/D measurements with a PIC microcontroller.
The PIC datasheet states that it has a source impedance of 10K.
Does this mean, I need to drive it with something that is lower in value so that it won't load the signal. I have a voltage divider connected to this pin (2 X 10K), the middle connection going to the a/d of the PIC. Any help would be appreciated.
Best regards,
Raj
