LM6172: SPICE model voltage saturation and recovery characteristics accurate?

Part Number: LM6172

Does the SPICE model of the LM6172 on TI's site accurately model the output voltage saturation and recovery characteristics?

Hey Ken,

Since there is no mention of overload recovery within the model, we cannot guarantee that this parameter is accurate during simulations.

Best,

I do not believe any op amp macromodel attempts to capture overdrive recovery time accurately -that is particularly true since it is often external circuit dependent.

Thank you both for your responses. I didn't expect the model would do so, but I thought I'd ask anyway. Thanks again.
