HI
I have to design an optocoupler circuit using the IL300 to isolate a DSP from the circuit from which it is monitoiring hign voltage signals that are stepped down before connection to the optocoupler.
Most of the spec sheets and application notes make use of opamps as amplifiers.
Can anyone please explain to me what the purpose of using an amplifier is? because as far as I can tell, I don't think that I need to amplify any signals.

That was the spec sheet I was referring to.
Any help would be appreciated.
