>There is no direct replacement for a LM324 family, since no other opamp family can safely handle voltages on the inputs well over the positive supply. ...
>Plenty do this. Search for "Over the top" or OTT inputs.
this was the source of my confusion. i can barely find any info on "over the top" op-amps and this poster was mistaken because LM324 isn't one of them. so there's not really anything special about LM324 other than its low cost, widespread availability and perhaps low power consumption (i haven't checked the power consumption)
