Does anybody know a good way to take the pulses from a rotary encoder and turn them into a DC voltage that would go up for clockwise turning and down for counterclockwise turning? I have the A and B pulses from the encoder, and that's about it as of yet. I also have these chips

and was thinking I could do something similar to what the datasheet suggested: use a digital potentiometer to get a linear gain from an inverting op amp. The only thing is that the AD digital pot they listed doesn't have the resolution I want, and the part count is starting to get up there.
I know this must be pretty standard from the perspective of robotics, and I'm thinking that there must be a good way to get an analog readout of the shaft position that I just haven't come up with yet. Any suggestions?
