SAR (successive-appoximation-register) analog-to-digital references have more influence on conversion accuracy than you may initially think. Figure 1 shows the ...

Analog-to-digital converters (ADCs) perform conversions by comparing the input voltage level against the reference input; therefore, the accuracy, stability and noise of the reference directly affect ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...

The voltage reference sets the limit to the input analog signal that the ADC can resolve. Equation 1 is the ideal transfer function of an ADC where the output code—in decimal form—is computed by the ...

When designing a system’s signal chain, lots of time is probably devoted to selecting the proper analog-signal driver for the successive-approximation register analog-to-digital converter (SAR ADC).

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...

CPF 2.0 was released more than a year and half ago, yet the majority of the designs are still done with CPF 1.1. This is one of those good news/bad news situations. The good news is that CPF 1.1 is ...
