Post subject:  LM748 Spice Model

Hi,

Can anyone point me to a spice model (using LMSpice) for the LM748 op amp? The simulation shows a reasonable waveform shape on VCA transistor collectors but the OP AMP output of the LM741 model that I am using only shows 1/2 cycle and I am wondering if it has to do with the model.

This is my first post - is there a way to attach files?

Thanks,

Greg

It turns out that I drew the schematic wrong and tied R74 to ground instead of Vr. The 741 op amp model seems to be working fine now.
