The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

The analog portion of the signal is becoming smaller and smaller as more and more digital signal processors (DSP) and microcontrollers are bringing their computational and timing strengths to analog ...

Many microcontrollers have built-in ADCs (analog-to-digital converters), which means you can use a single device to both digitize analog signals and manipulate the results. Once the ADC digitizes a ...

A look at the design of traditional ADC front ends. How to simplify the input drive of CTSD ADCs. Simplifying reference and reference-drive designs. In this article, we will use the terms “sensor” or ...

Past columns have discussed sampling analog signals and analog-to-digital converter (ADC) technologies. In my experience, though, engineers who simply want to use ADCs rather than design with them, ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

The ADG1712 from Analog Devices integrates four independent CMOS single-pole, single-throw (SPST) switches capable of ...

Confused by analog-to-digital converter specifications? Here's a primer to help you decipher them and make the right decisions for your project. Although manufacturers use common terms to describe ...
