Friends, I have a project where I need to read an analog voltage of +7V-+18V. It is an internal power monitor of a RF amplifier. I am using it in a test fixture and was hoping of some way to read the voltage to know how many watts are at the output of the amp, without using a power meter. Does anybody know of an A/D converter that goes that high? Does the PICs internal A/D go that high? Any ideas?? Thanks in advance.............................
