Current-feedback amplifiers have a higher slew rate than do voltage-feedback amplifiers. As such, current-feedback amps can better solve high-speed problems than their voltage-feedback counterparts.

A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic ...

NAMM 2025: AmpRx has unveiled Brownie, an voltage optimising power supply that’s designed to give your tube amp exactly what it needs to perform at its best. Now, AmpRx has made voltage attenuators ...

NAMM 2025: AmpRx has sought to shake things up for tube amp users by releasing the Brownie – a nifty voltage controller tool that looks to optimize the tone and performance of valve-loaded guitar amps ...

Normally when we hear of a Champ guitar amp, we think of a sweet-sounding rig that puts out 6 Watts through an 8-inch speaker. [John Chambers] of Champ Electronics wanted to build a true champion for ...

When designing circuits, power dissipation is often a big issue. One way to reduce power consumption is by using linear active components such as op-amps. The following application note shows multiple ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...
