Are there resistor networks which could function as a pre-made voltage ladder? In other words are there variations on how the resistor network is assembled, ie in series or parallel? I've found these but am not sure how they are assembled...Thanks
Or these kinds:
If you need a ladder, you can buy a network and connect the terminals. Why aren't there more configurations? Because manufacturers don't want to exclude customers options with a more specific configuration.
There are also precision networks that have better tolerances and resistor matches in one IC
The only other place where I think you'd see custom resistor ladders is in the high voltage sector where spacing is important to prevent arcing.
