App note: How to save power in high-precision measurements

App note from Maxim Integrated on achieving a lower power sensing in analog front end. Link here

In precision signal conditioning and measurement applications, a delta-sigma ADC has often been preferred over a SAR ADC on account of high-resolution output and highly integrated internal blocks such as a PGA or GPIO voltage reference. However, in some circumstances, the delta-sigma ADC’s high resolution is not needed or cannot be achieved, and its high-power consumption becomes a drawback.
