Hi Michael, The TI white paper you refer to was written before we had SNR data for several of the ADC's using this feature. The parts can meet SNR specifications when following the Zone 2 guidelines in Figure 46 of the datasheet. For the ADS8910B you have 950nS in Zone 2 to transfer the data without degrading results. I checked the performance on the ADS8900B EVM (20b version of the ADS8910B ), and it showed no degradation when going from Zone 1 to Zone 2. I also verified that it used about 800nS of the 950nS window to transfer the data. I hope this helps. Regards, Keith
