    When i power up my circuit board my ADC0804 is heating. I had nothing given at ADC0804 inputs.

     

    For refrence i had attached my circuit diagram.

    Every thing is working fine without inseting ADC0804 to my circuit board.i.e.LCd,Relay,Keyboard,Micrcontroller Time etc.

    As i insert the ADC in my circut it takes a high current and heating up. I had check Vcc-Gnd is not shorting in my board specially in the ADC section.

     

    Pls help me out in this problem.

     

    Thanks in advance.
