Comparing Voltages in (Very) Tight Spaces: A New Comparator from Maxim

Components that use wafer-level packaging (WLP), such as the MAX4000x series, are valuable options when size reduction is a critical design goal.


Fast, Ultrafast, Soft, Standard, Schottky: Selecting the Right Rectifier

Fast, Ultrafast, Soft, Standard, Schottky: Selecting the Right Rectifier

This article is a deeper dive into the speed-related recovery characteristics of rectifiers, and how this dynamic behavior has significant effects on the circuits in which the rectifier is placed.


Fast, Ultrafast, Standard, Soft, Schottky: What’s the Right Rectifier for Your Power Circuitry?

Fast, Ultrafast, Standard, Soft, Schottky: What’s the Right Rectifier for Your Power Circuitry?

This article will help you understand rectifiers: how their static behavior differs from their dynamic behavior, and how “speed” is used as a defining characteristic.


Addressing Harmonic Distortion in Audio Amplifiers

Addressing Harmonic Distortion in Audio Amplifiers

Harmonic distortion can be introduced to audio amplifiers from many sources but reduced to levels below the threshold of human hearing.


Less EMI, More Available Board Space: A New Passive Filter from TDK
