Hi all, I realize I'm asking for the world here, but google hasn't been very helpful. I've found a few candidates with some/most of what I need, but wondering if there is some holy grail op amp out there that everyone is using. I'm growing tired of making work-arounds for the LM324's I have laying around. I'm looking for a commonly available op amp (or multi opamp package), 8-pin to 14-pin dip with the following attributes. Rail-to-rail capable. Single supply or dual supply. Can source or sink about 20 mA. Has internal protection for common-mode input voltage beyond supply voltages. Has internal protection for differential input voltage beyond supply voltages. (And the usual, internal, ESD protection.) Output does not exhibit phase reversal when inputs are beyond supply ranges. Preferrably robust for harsh environments and not requiring a lot of anti-ESD precautions during handling. I don't need very high freq capability, probably audio range or even slightly less. I just find my projects are always limited on space, hence the internal protection components would be nice. It usually ends up in automotive type environments. One thing I haven't found, so am wondering if it even exists, is internal protection for input voltages where the protection doesn't greatly affect the input impedance. I realize this feature might be physically impossible, but in case there is some magic op amp out there, I thought I'd ask. Thanks for any help.
