AD8552 spice model

Hi

I found AD 8552 spice model not working properly.Initially the file was not reading , then I found  there is two "dots' in before "subckt" declaration and I changed it and my spice program ( LT Spice) started reading. But I got a model without any labels, please check the attached image. I probably can do a trial and error to find the pins, but I am just wondering there is an updated model?

I have one more question. Is there any design or manufacturing change made to this particular amplifier recently (in last 5 years) because we are seeing some problems recently (in a nutshell a floating ground on output)? This question is a separate discussion but I am just wondering

  • NM,

      -- LTSpice has a generic op amp symbol.  Some how, you have told it to generate a symbol, so it only

    knows about inputs and outputs and power.

    --  The AD8552 product page has links for the PCNs for each line item.  2010 fab transfer and 2011

         halogen free epoxy adopted.

    --  "A floating ground on output"  makes no sense.  Can you supply a schematic?

    --  Why are you using a 13 year old part, when the AD8629 is the second generation, with better specs

       and lower price and a newer, better spice model?
