(AD8418A)Vout ≠ Vref

Hi !

 

I have a question about AD8418A.

This is my test circuit.

 

 

I measured the Output voltage but it is not Vref level.

=> I don't have AD8418A so I measured AD8418.

 

Why this happens?

Our customer said that  this won't happen when they are using AD8206

but I measured AD8206 at my Lab and same thing happened.

But the output voltage offset is smaller than AD8418.

 

I think that maybe the +IN pin leakage current is big 

Can you explain that why this happens?

 

Best regards

Kawa
