I've been tasked with building a digital to analogue converter for my class. Like so:
https://www.electronics-tutorials.ws/opamp/opamp11.gif
It needs to have 5 volts in on the inputs and 1 2 3 4 on the output corresponding to pressing 1 2 3 4. I understand how to do this, but I don't see why I can't just accomplish this with a voltage divider. If I eliminated the amp all together I think the circuit would achieve the same thing.
Thanks guys!
