with high precision required. The domain is aero. How can I simulate, with
spice, the AD8295. Do you have a model ? Must I use several discrete models ?
Which ones ?
The AD8222 spice model will work for the in-amp part of the chip. All simulated
parameters are the same. Unfortunately the two op amps on the chip have no
spice model. I think the easiest thing to do would be to use Multisim’s 5-port
Virtual op-amp (OPAMP_5T_VIRTUAL) and modify the parameters to match the
datasheet. It does most of the work for you. You also have to go in and modify
the actual netlist to get the input and output clamps right. But it’s much
easier than starting from scratch and more accurate than picking a “close
enough” op amp.
