ADC0804 is heating up when power up my circuit

[Japs]

 

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.

Could you please seperate out the images of each section like microcontroller section, voltage measurement section etc. and post them as seperate images.
