    Hi Marceli, the output current of XTR111 must be limited to less than 50mA or you risk that the XTR111 becomes damaged. The XTR111 is not designed to output a current of 100mA. I would think about using the improved Howland current pump: 3835.snoa474a…

    Hey Dan, LM120K-5.0/883 is indeed obsolete. I've attached the PDN. We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives. ~ Aaron PDN 200824.pdf
