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
-- 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?
