I have a board from a Mitsubishi CNC mill its a MDS-A-SVJ-03 servo control unit. It is giving a current sense error i think it is related to what i believe is isolation amp (hp7806) chip, used to read voltage drop on a shunt resistors on the HV side. ( I say this because i have only found data sheets for this chip http://pdf1.alldatasheet.com/datasheet-pdf/view/64642/HP/HCPL-7800.html which seems to have the same pin out (at lest on the high voltage side.)

I am trying to find replacement hp7806's (i need two) any ideas as to where to go to find them..

Thanks Daniel
