  • RE: OPA189: About its output stage

    Xueliang, Even if your external representation of the internal OPA189 output impedance is perfect, you may NOT expect the same behaviour with the composite configuration because in the later case any signal undergoes double delay and additional phase…

  • OPA189: Vf value of internal diode

    Part Number: OPA189 Hi Team, I'd like to know the Vf value of internal diode of OPA189 to design external input protection circuit. because an external protection should be work faster than internal circuit. And if you have official document of detailed…
