How can I tell if an IC is resistive or not?
I'm looking at LTC4357 & UC2907.
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.
