1.11 QUIET INTERFACE MODE
To improve performance at High Speed, operate the ADC in
Quiet Interface Mode. This mode provides improved INL and
DNL performance in I

Quiet Interface mode will only improve INL and DNL perfor-
mance in Hs-Mode. Standard and Fast mode performance is
unaffected by the Quiet Interface mode.
