hi,
That link is not a analog to digital convertor, its basically a temperature sensitive bridge, using 3, 10K0 resistors and a thermistor.

You would need to amplify the output of the bridge before the signal was input to a A2D convertor.

Look at the ADC0801 ic series, they will operate as a 'stand alone A2D', also with a differential input to suit the bridge.
