Hi Anna
In the pspice model of ADA4870 , just some of pins of IC is considered as :
* Node Assignments
* Non-Inverting Input : 100
* Inverting Input : 101
* Positive supply : 102
* Negative supply : 103
* Output : 104
* Shut Down BAR : 106
And some nodes like “ON_bar” isn’t considered !
Art first I created a schematic IC by “ Component wizard “ and load spice model into that, in Miltisim environment and then I configure a simple non inverting amplifiyer by this model. But in simulation it doesn’t work .
I had attaché the multisim schematic and psipce model and picture of schematic and picture of output curves in this email.
Please simulate it and observe the output curves . the output curves is nor reasonable ! the output is a 0 volt DC ! it hasn’t any error and output isn’t reasonable !
