Primary use is as low gain, low Bw signal buffers here and there, mux buffers, etc , i dont have any space for additional components, The whole design runs from +/-7.5V from that i need an absolute min of +/-5V out swing. But i would certainly not say no to full rail to rail.
Just saw that TL064IDT and TS274CDT at pack of 500 units have almost identical price yet both past 6months been upped by 80% by the usual oligopoly suspects, have to look for other sources.These two are hard to beat price wise.
TLC274 and TLC2L74 and TLC2274,LMC660 is out, way ludicrously expensive.
