Most digital-to-analog converters (DACs) are operated with a fixed positive reference voltage and output voltage or a current that is proportional to the product of the reference voltage and a set ...

Analog-to-digital-converter (ADC) resolution and sampling rates keep pushing the envelope. And every time they push further, it gets harder to match the ADC to an input amplifier in high-end test and ...

Waltham, Mass. — Instrumentation amplifiers (in-amps) are specialized, precise-gain op amps with a challenging task: They take a low-level input signal, such as an EEG or strain gage, which is ...

Can a 32-year-old all-analog NAD 3020 amp blow away a shiny-new NuForce Dia all-digital amp? Steve Guttenberg Former contributor Ex-movie theater projectionist Steve Guttenberg has also worked as a ...

When using an active front-end amplifier to drive a high-speed converter, designing an anti-aliasing filter (AAF) can be a difficult task. It’s important to get it right because anti-aliasing is the ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...
