Hi
I just want to get some idea how to use an OTA as an integrator (for dual slope ADC). Can some one help me out or give me some links?
Thanks

You charge a capacitor with the signal output current, and then discharge it with the reference. Not really sure what you are asking. Read the dual slope A/D article at wikipedia. I think the only difference with an OTA is where you put the capacitor.
