Thank you very much Helmut. I can handle all of that myself. I am just studying OP-Amps also and need this one for a color organ circuit that I need ?figured out. Best Kevin.

I down loaded a OP-AMP I need to study like your TL072 verses LT1057
Folder. Question What do I have to do in PSpad and or on schematic to use the Universal Symbol "opamp2.
It states: * LF353 OPERATIONAL AMPLIFIER "MACROMODEL" SUBCIRCUIT
.SUBCKT LF353 1 2 3 4 5
Is this just a .include LF353 .SUBCKT LTspice directive on schematic.
or do I have to open a window & change parameters again and if so what should it read for a OP-Amp instead of a Zener Diode. I just need the info to store in my collection of files for all types of parts introduced into LTspice so in the future I have help all figured out
if it is not a problem in a little bit of a guide not a drawn out affair. Best wishes Kevin
Hello Kevin,
You can use the symbol opamp2, because it has the same pin-order
+in -in V+ V- out.
You will need then only an additional .include LF353.mod in
the schematic.
The value have to be LF353/NS, because it's the name in the
.subckt line.
You can look-up an example.
