Photodiode Array Possible?

I found something interesting and might help me with the project. However, I have no idea how I would program with this.

8-Channel Analog Multiplexer with Serial Interface

I found this trying to do some research on multiplexing. What is cool about it is that you can daisy chain them for a ton of analog inputs only at the expense of 1 digital port!

Like I said, I have no idea how to program this yet, but does anyone think I am on the right path here?
