Analog-to-digital converters (ADCs) are used in a wide range of electronic devices. However, most of the low-cost microcontrollers do not include an ADC peripheral. This design idea provides a way to ...

How to measure linearity of an ADC using sine-wave input. How do non-idealities of a sine wave affect ADC linearity while testing it. Testing an ADC’s linearity. To obtain the transfer function of an ...

For convenience here are pdfs of part 10 and part 11 of the series dealing with ADC noise issues. In the previous part of this series, we discussed about noise basics and how they affect an ADC’s ...

A 32-bit successive approximation register (SAR) analogue-to-digital converter with dual outputs and digital filters to optimise signal bandwidth has been introduced by Linear Technology, now owned by ...

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 ...

Let’s say you chose a particular microcontroller for its 12-bit analog-to-digital converter (ADC). You built up your system, and although the ADC gives you 12 bits of resolution, the lower couple of ...
