Multi-part component simulation with LTSpice

Question

Hi,

I would like to simulate my circuit containing multiple opamps (AD8656) residing in one common package. I have created the library in Eagle for the component containing both parts (2 symbols, 1 package).

I was able to export the corresponding LTspice library, but only the first opamp simulation works. The spice model contains the subcircuit for one opamp only.

Eagle exported the two parts into separate LTSpice libraries AD8656G$1.asy and AD8656G$2.asy.

If I look into the second library file (AD8656G$2.asy), The part has no V+ and V- pins assigned, therefore it does not work.

How can I create and export a multi-part component to work with LTSpice?

Thanks,

Hi Zoltan,

the problem seems to be that LT Spice can't handle compnents that consist of more than one gate. So your opamp has to have both gates in one common symbol. If you 'ld change the library definition in EGALE it should work with LT Spice.
