Do I need a multiplexer?

[Callum121]

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!

What is the brand and model of your sensors?
How about a 4017 counter IC to activate each of the 9 current-to-voltage converters in sequence?
What type is the serial input interface on the evaluation board?
