I'm wondering how I would sample an analog input with range say 0-24VDC with an ADC that does only 0-2.4VDC? My first thought is an opto-isolator with transistor or darlington output but it doesn't seem right or complete anyway.
My other thought is that I will be somehow compressing the analog signal so I might lose effective resolution especially if the signal is changing quickly. So I might want to up my bits of resolution to to compensate.
Is there a name for the type of circuit I want to make? Thanks.
