LF411C

Other Parts Discussed in Thread: LF411

Hello,

I have downloaded the Pspice model for the LF411C and created its symbol.  When I try to simulate the circuit, I get the error saying that Pin1 through Pin5 are

not in the template.  The subckt has the pins from 1 through 5 and without knowing which pins correspond to which pins in the datasheet, the simulation will

fail.  I think that's what's happening.  This is a 7-pin device.  I thought that the two missing pins are the power pins., so I assigned the pins

and added twp power pins in the symbol.  It didn't work.  I think that the "Order" in the part property is messed up.  I don't want to spend time to try assingning

different ways.  Does anyone have the correct part property that correspond to the subckt for LF411C? 

Thank you,

    Hello,

    LF411 model / symbol is already included in TINA (if that is simulation platform you are talking about?). I've attached a TINA file which has the LF411 and shows 5 pins (2 inputs, 1 output, and 2 power pins).

    6521.LF411 5_14_13.TSC

    Hello,

    I downloaded pspice model for lf411 so that I could create the symbol and simulate the circuit using the schematic capture.  I was using spice simulation tool not TI-Tina tool.  The simulation failed.  I looked at the subcircuit for lf411 and there was no information on which pin corresponds to which pin function that matches the datasheet.

    I found the information elsewhere regarding which subcircuit pin matches which pin on the datasheet.  I try this info and if this fails, the problem is something else.

    Thank you very much for your help.
