The model for the LME49710 does work but it also throws a warning in LTspice. Specifically, it complains that the nodes of capacitor Cc4 are shorted together. I examined the attached LME49710 model and identified the source of this warning in line 95:
C_Cc4 GND_FLOAT GND_FLOAT 4.11f TC=0,0
This defines capacitor Cc4 as having both terminals connected to GND_FLOAT.
This doesn't seem to affect a simulation, as LTspice ignores the error, but does anyone know what correction needs to be applied to this line in the model?
Also, I found a National Semiconductor model for the LM4562 (attached) which appears to work well and doesn't throw any errors or warnings. I've used this model in several different circuits and haven't encountered any problems with it yet. Maybe this will work for others as well. This model can be used with the built-in LTspice opamp2 symbol. The LM4562 really doesn't require a special symbol.
