Re: Best Choice
@samicksha: Im kind of confused. Is there a particular percentage involved or has any direct impact towards it ?

Clarification on "AD8031 is a good choice.."
This article and a couple of other reference materials (including the evalboard for AD7960) are calling for the AD8031 as being stable with high capacitive loads; the AD8031 datasheet has a different story on page 15 (chapter "DRIVING CAPACITIVE LOADS"); am I missing something?

Re: Best Choice
To avoid conversion errors, the average current required at a particular throughput should not cause the reference voltage to droop more than ½ LSB.

Is it we can ignore the conversion errors...

A poorly designed reference circuit can cause serious conversion errors. The most common manifestation of a reference issue is repeated or “stuck” codes from the ADC
Once the drive capability has been determined, we must ensure that the noise from the reference circuit does not affect the ADC’s performance.
The overall precision of a high-resolution, successive-approximation ADC depends on the accuracy, stability, and drive capability of its voltage reference.
How much power does your ADC draw? The spec sheet may provide the answers -- but read the fine print.
