i am having trouble with the input of a adc 0831 varing up and down. Is their some kind of filter that can stablize it. I am using a 14 vdc power supply to simulate a battery. The power supply is well regulated at the output.·I am·building a battery charger.

    You you give more of an explenation? How do you know the input is going up and down? What are you using to feed the input? How are you measuring it?

    Also,

    ··· Where is the 14V going to?··The ADC0831 is a 5V device and cannot be powered by or measure anything over 5V without bringing it down somehow, for example a resistor divider for the input.
