Re: ADA4870 high output current op amp

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 !

Sadegh
