Waseem,

You can refer to the ADC timing diagram in the datasheet for the conversion delay. Applications can compensate for the trigger delay + S/H times by triggering the ADC conversion earlier.

I suppose your error would be a phase delay.

Thanks a lot for this.
But i am not able to understand these timing diagram.
Can u suggest some document from where i can understand in a simplified manner
waiting for your reply

Waseem,

The ADC Reference Guide has additional information on ADC operation.
