Ok so here's the deal:
I have a variable DC Voltage source from 0-10V.
I need to step that down to a variable source of 0-3V.
This 0-3V DC will be fed to an Analog to Digital converter in a microcontroller.
I know I can potentially use a Voltage Divider (using resistors) but apparently, that's not a good solution.
Op-amps don't provide a gain < 1.
So I'm just struggling as to how I can accomplish this.
