    How can I tell if an IC is resistive or not?

    I'm looking at LTC4357 & UC2907.

    Thanks!

    Welcome to all about circuits.
    What on earth, or a pc board, do you mean?

    Are you referring to the output resistance of the device?

    I think the OP wants to model an IC as a resistor. ICs typically have non-linear characteristics.

    I would say an IC can be modeled as a resistive load, as compared to capacitive or inductive, but it can not be modeled as a single resistance value. The current changes as the IC does its job. In addition, some ICs deliver current to a load that might be capacitive or inductive, and that would make the circuit as a whole very different from only considering the IC.
