Hi
I'm trying to find a way to describe how the current outputs of a dac behave (e.g. TDA1541 or even TDA1547).
I'm pretty sure they're not perfect current sources... 😕
So how would you approximate them?

I Think they're more perfect current sources (AC and DC for offsets) with a parallel resistor...
After all they are a bunch of switched capacitors, which store charge and deliver current into a load (=I/V resistor)
Unfortunately I have no idea how to check this (measure it).
Got some info on how TDA1541 is supposed to look like, used a similar model for the 1547 dac outputs and the results seem to match the datasheets after some tweaking.
