AD711 Noise Figures
Looking closely at the datasheet, in particular the noise density graph, we can see that the figures appear to be at (close to) 10Hz and each decade above that to 10kHz.
As this is effectively the 1/f ...

Transformer-coupled low noise amplifier
One possible problem: the shorted primary is a fairly sensitive magnetic field meter. Take a look at the output of the amplifier with a spectrum analyzer.
When I open the primary short, the noise ...

FPGA controlled ADC has undefined data
I wouldn't worry about it. This is a very simple, low-latency SAR type ADC. The chip select controls the sampling, and the first data bit is output on the second clock cycle after that.
As far as I ...
