Let’s Compare SAR & Δ-Σ Converters for a Mux’d DAS, Part 2

In part 1 of this series, we started looking at the differences between the successive approximation register (SAR) ADC and the delta-sigma (Δ-Σ) ADC. We looked at how they work and some advantages ...

Basics of ADCs and DACs, part 1

A block diagram of a typical sampled data DSP system is shown in Figure 2-1. Prior to the actual analog-to-digital conversion, the analog signal usually passes through some sort of signal conditioning ...

Power-Saving A/D Conversion for High-Accuracy Measurements

For power-saving or battery-operated measurement applications, combining a SAR ADC and instrumentation amplifier offers a better solution than a sigma-delta ADC/PGA combo due to its lower power ...
