Do I need a multiplexer?

Hi
For my final year university project, I have an array of 9 hall effect current sensors producing a maximum current output of 25mA each. They're producing an analog output which I need to convert in to digital signals so I can process them using an evaluation board and C++ code.
At the moment I'm thinking about using an analog multiplexer to cycle through the 9 inputs (using C++ code somehow?) one by one, then using an a single input ADC to convert them to digital signals.
Is there such a thing a multiplexing ADC?
The evaluation board has a serial input port.. so would I even need a multiplexer?
Any thoughts?
Thanks!
