The input transformer is likely to be the most expensive part of the entire project. As an alternative, a couple of 12 Volt car batteries could be used. The input voltage to the regulator must be at ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Apex Microtechnology has expanded its portfolio of high-voltage operational amplifiers with the PA99, an off-the-shelf, single-package 2500-V power amp that addresses the demand for high-voltage ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

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 ...

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 ...

Considering their differences in design, you might wonder if you can jump-start a V8 with a four-cylinder car. The answer ...

Have you ever wondered how a car engine starts? Or how the air conditioner turns on when the car is switched off? The answer to these questions is simple: the battery plays an essential part in the ...

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 ...
