Simple Amplifier Options Improve Dynamic Range in ADC Interfaces

By Michael Steffes
In a signal-conditioning op-amp application, is there an optimum circuit topology for optimizing SNR and SFDR?  Here’s a succinct analysis, part mathematical, part simulation, and part cookbook, from
Electronic Design's Don Tuite and Intersil's Michael Steffes that presents the case for transformer-coupling the signal and applying it to the op-amp’s inverting input.  (Direct coupling and transformer-coupling to the non-inverting input are analyzed and shown to be inferior.)  Brought to you by Intersil.
