Hi NITH, On the LPC1768, it is a 12-bit A/D, but the usable bits may be fewer, due to sensitivity to noise.
Please review the following articles:
- AnalogIn problem - a rather extensive review
- search for "noise" on this site
- Links to the chip data sheets

You could try to enhance the 12 bit resolution by oversampling.
There is a nice explanation how it works with AVR's at the Bascom site: http://www.mcselec.com/index.php?option=com_content&task=view&id=325&Itemid=57
