MS 12.01 Component has several models: How to select correct model

[Who_Knew]

Hello,

When I select a component from the Master Database, sometimes there are several simulation models avaliable for it.  How can I tell which is appropriate for my use?

For example, TLC2227 is an opamp from Texas Instruments.  As far as I can tell, it's available in 3 packages and 4 temperature ranges.  The MS Master Database has 5 models to chose from, with no way to know the difference between the 5 unless I want to try to decypher the model code.  How should I know which one is appropriate for my use?

Hi,

If you find the model you want (So say TLC2274CD) and hit on detail report, you might get a better report on what each model does. The models are created by the manufacturers and most of the time they are created to vary in complexity. Some will give you more accurate results but will require more processing time while others will give you less accurate ones but being easier on the simulation. It is up to them to relay the information in each model they make and if they don't we cannot have a sure way of knowing unless you look at the SPICE code. Short answer is yes you have to look at the code itself, usually they vary in degree of complexity (most of the time you don't really need super complex models).

Kind Regards,
