I'm trying to model some simple electric/electronic circuits using DAC pins as power sources. Something like this, but with different voltage and resistance values.
I want to know how much current a DAC pin can draw (in case when current flows from one source to another due to voltage difference between them). Is it possible to model something like this without a risk of frying Due?
Another problem is, I am going to output sine waves from DACs, and so there will be capacitors in my circuit to remove DC offset from each DAC, and the circuit I am modelling consists almost entirely of inductors. Should I put some sort of circuit protection in my scheme in case negative current flows back to one of the DAC pins?
