NOTES

The schematic at left should tell you everything you need to know about how to run a single channel A to D converter.

It is controlled by the same commands that operate any shift register. EXCEPT that the 0831 sends out a dummy byte for the first clock pulse while the internal histerisis settles down.

Most interesting: changing the value of the resistor on the REF [pin 5] will change the value and range of your input. Try it when you are debugging your sensor for the most desired signal range.

0831 Datasheet

Analog To Digital Converter

For this example I used the Texas Instruments model [prefix TLC].
There are many different manufacturers, but the 0831 is always the same.

Part number -0832 is a dual channel A to D.
I will post sample circuits and programs using it soon.
