Hey everyone,

I've looked around for app notes or books on circuits that can scale either a DC voltage or DC current linearly to a value adequate for an ADC. For a voltage so far I know of a resistor divider and for current its either a sense resistor or hall-effect sensor. Are there any books, articles or notes that provide a bigger range than this? I would just like to do a comparison of the different techniques, their accuracy, linearity and speed.

Thanks in advance for any help
