Hi Ermine,
Thank you very much for your reply! Yes, I did see the datasheet. But my concern is whether the model of AD620 in Multisim will reproduce the same. Actually, I wanted to use this component as part of a bigger circuit. The working of the circuit will be in high-frequency range (of the order of megahertz). So, I wanted to know if the Multisim model of AD620 will show its frequency dependent behaviour as mentioned in datasheet. If it does not the whole point of me doing the simulation will reduce to nothing.
