  • LF411: BAL pins unconnected

    Resolved
    Part Number: LF411 Hi all, I need to use the LF411 amplifier for a project (i.e. replacing it is not possible). I could not find much information about the balance pins (i.e. pins 1 and 5). If it is not necessary to trim the input offset voltage, is it…

  • LF411: Resistance of pin 1 and pin 5

    Resolved
    Part Number: LF411 Hi Team, Previously purchased LF411CN, the resistance pin 1 and pin 5 is 24KΩ. Then replaced LF411CN with LF411CP, and the resistance of pin 1 and pin 5 is 2KΩ. It is reasonable to say that the resistance of alternative part will not…
