Design FAQ: ADC Front Ends With Fully Differential Amplifiers (FDAs)

Minimizing noise in the signal chain between sensor and ADC is always tricky because all the elements in the chain interact. Even the position of active and passive elements in the signal path can be critical. Here's a high-level view (with a link to a more rigorous analysis) of a signal conditioning approach that takes advantage of the latest in differential op-amps.
