LOG100's input current is positive current, andit means usually the input current can only flow to pin 1 and pin 14. In some applications, the signal current is negative current , such as photomultiplier tubes. The circuit can solve this problem, which uses the circuit in the attached diagramto convertnegative signal current to positivecurrent inflowing toLOG100.
