Some techniques for direct digitization of transducer outputs (20)
Analog-to-digital conversion circuits which directly digitize low level transducer outputs, without DC preamplification, are presented. Covered are circuits that operate with thermocouples, strain gauges, humidity sensors, level transducers and other sensors.
The care and feeding of high performance ADCs: get all the bits you paid for (21)
This application note describes proper techniques for applying high performance ADCs. It describes the problems designers encounter, how to recognize their symptoms and how to avoid them. Topics include ground planes and grounding, supply and reference bypassing, analog input signal conditioning, sampling clock generation, ...
