"Dual supply" = this op-amp cannot output to either power railCould anybody give some basic idea ???
Yes, and I'm not sure whether the input or the output range is more often used for classifying the op-amp. I also don't know where the lines are drawn. I mean, an op-amp that can output within a few mV of the rails will be called rail-to-rail, but if it's more than say 100mV away from the rails then I think it would be misleading to use that term.Note that input input common-mode voltage range also generally corresponds to the output voltage range for those three types of op amps (although there are some exceptions).
I'd say that in most designs, you worry first about current and voltage requirements along with frequency of the application. Then you can worry about the which type would simplify your circuit. Why not use rail-to-rail for everything? You certainly could, and it might be a great choice for DIYer to keep a handful of R-R op-amps on hand. But they tend to cost a bit more and often there's no need for it. Personally I have a handful of LM358 on hand because they're cheap, ubiquitous and work well on single supply. I got a couple TLV272IP (R-R) when I needed them for a specific project.How to select these opamps in practical applications ???
It depends on your application. Some require rail-to-rail inputs and/or outputs, some require low noise, some require high bandwidth, some require high slew rate. Pick the one that satisfies your important requirements.How to select these opamps in practical applications ???
I suggest you try, it will work.I did.
The data sheet states the common-mode range is 1.5-2V below the high side voltage, so I don't see how it can be used as a high-side current monitor.
Not explicitly.No where have I suggested that the inputs would be connected directly to the same voltage level as the the LM324's supply voltage.
One feature is its use as a high side current monitor OPA, due its input design, refer the datasheet.
