  • RE: Power supply sequence of OP2177


      The OP2177 is junction isolated on P-type starting material so the V- pin is the substrate.

    You should apply V-, then V+.

      For shut down, remove V+, then V-.

    Also note the ADA4077-2 is a next generation version of the OP2177.

    The OP2177…

    Take a look.


  • ADA4077-2 VOS differences between MSOP and SOIC Packages

    Why a difference in VOS specs between the MSOP and SOIC?


    ADA4077-2 has a “B” grade (SOIC package only) and an “A “grade in SOIC and MSOP
    package.  The difference between different grades is Vos parameter. Grade B has
    a VOS specs of…
