I used LTspice to design an oscillator using the LT6012 Op-Amp only to find that there's no stock available anywhere. The MAX44245 seemed to be a good sub and it has a model in the standard LTspice components library. However, the simulation runs a very long time without completing where the LT6012 part model runs very quickly without a problem. I need to find a good sub for the LT6012 that is: (1) spec'd. for +/-15v supplies, (2) is available in distributor stock, and, (3) has a model that will run in LTspice.
