Re: Current ampilfication

Yes, classic OpAmp current source/sink can be done with onchip

   

OpAmp and external Rsense and a discrete transistor. Using onchip

   

VDAC one could drive that into aforementioned solution and effect

   

current multiplication.

   

 

   

1) Is your current DC only ?

   

2) Accuracy of desired current ?

   

3) Complience range of source/sink needed ?
