At the beginning of this year, I built a DAC using the AK4498EX, which I dubbed the ultimate USB bus-powered DAC. Since then, ...

If you go out and buy a high end pair of headphones and plug them into your onboard audio you are essentially doing the same thing as buying a 4K monitor and plugging it into onboard video; sure it ...

Building on last month’s discussion of resistor noise, let’s check out some basics of amplifier noise. The non-inverting op amp configuration is most common for low noise applications so we’ll make ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...
