I'm using the datasheet spec's at 9.7 MHz (datasheet pp 5, VREF = 1.4V for best performance). Our signal frequency is more like 2 MHz and we will run at the minimum sampling frequency of 40 MSPS using a 160 MHz input clock. The general question will the SNR,SINAD,ENOB numbers not degrade from the values at 9.7MHz? More specifically I'm hoping that they would actually improve slightly and if so by how much? Thanks in advance for your time and attention.
