THS4631

[mosfet50]

Hi can someone please give me the MODFILE data for the THS4631, I think I accidentally goofed it up.

MODFILE is OA_BIP, I need SPICEPINS, PRIMATIVE, ETC.
Thanks for your time and help,

MODFILE is OA_BIP, I need SPICEPINS, PRIMATIVE, ETC.

OA_BIP is a model for BJT-input while THS4631 is FET-input OP so you need OA_FET model.
Also, OA_FET (as OA_BIP as well) is a schematic model so you don't need SPICEPINS or whatever.
What you need of is only a list of numbers - you can get from datasheet - which will approximate the THS4631 characteristics.

So, when you have created a suitable schematic symbol for THS4631 the only thing you need to do is adding the below properties to the 'Other Properties" field:

Code: Select all

{MODFILE=OA_FET}
{GAIN=10k}
{CMRR=56k}
{FT=325M}
{SR=1000M}
{IB=100p}
{IBOS=100p}
{VOS=0.5m}
{VPLIM=1.5}
{VNLIM=1.5}
{VALUE=LF351}

The last property is the prevent the error message "Value 'THS4631' of VALUE not found in parameter mapping table of sheet 'U1'"

Thanks for your help.

I added the properties you listed below changing the "value" to THS4631, this is what I got, which are the pin values from the part I created. I wasn't sure what parameters the program was looking for.

The OA_FET model requires the pins have to be named following these conventions (without double quotes):

Code: Select all

"POS IP"  for non inverting input
"NEG IP"  for inverting input
"OP" for output
"V+" for posistive power rail
"V-" for negative power rail.

When you have made your part - named as THS4631 - you should add manually in "Other Propeties" the property VALUE=LF351 once you place the part in the schematic. This is a dodge needed as the model uses VALUE to select the appropriate model data from a list of mapped table indexed by the op-amp name. I'm conscious this is not comfortable but it's the only way to prevent that message at the moment.
I'm going to modify the model removing any limitation.

I attach here an example for your convenience.

Thanks Ettore, very helpful.
