===============================================
Hey guys,
I'm trying to use the adc2x400-14, a 14-bit ADC part being clocked at
256 MSPS.
When I run the adc with zero input, everything looks good. However, if
I put in a sine wave (or anything, really) -- I get this (see figure).
Looks like it has a bunch of outliers. They're not all the same code
(see histogram), but they are coherent with a specific phase of the sine
wave (plus or minus n*pi).
This happens in both ADC channels, although this figure is just of one.
Any ideas? Thanks!
