TINA/Spice/LM7321: Pin Mapping of PSPICE model?

Azad Jalali
Prodigy 40 points
Part Number: LM7321
Other Parts Discussed in Thread: TINA-TI, , THS4131

Tool/software: TINA-TI or Spice Models

Maybe I'm missing something, but shouldn't the model file for the LM7321 have comments mapping the SPICE pins to the IC pins? Something like this (taken from SLOA070 for a different part):

* CONNECTIONS: NON-INVERTING INPUT
* | INVERTING INPUT
* | | POSITIVE POWER SUPPLY
* | | | NEGATIVE POWER SUPPLY
* | | | | OUTPUT +
* | | | | | OUTPUT -
* | | | | | | VOCM
* | | | | | | |
.SUBCKT THS4131 1 2 3 4 5 5b 17

Instead, all I see is this:

.SUBCKT LM7321 3 4 5 2 1

Can someone share the pin mapping for 1-5?

Thanks,

Azad

    That's bizarre, those lines previous to .SUBCKT aren't in my model file from your site. I wonder if the comments before the first line get cut off by Micro-Cap. Anyway, thank you for the quick response!
