What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

Introducing a non-gamer to cooperative play can be difficult. Games that overwhelm players with complex systems or rapid inputs tend to push newcomers away rather than invite them in. The strongest co ...

FiiO’s $989 K17 is a feature-stuffed DAC amp with real power, a 31 band PEQ, streaming, and smooth neutral sound. One box to rule your desk and shame your dongles. FiiO is on a 2025 release spree that ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

Operational amplifiers (op-amps) are almost the perfect amplifiers. As long as you keep a few important details in mind, they will seem perfect. In part 1, I gave a simplified explanation of how an op ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

A persistent issue with Op-Amps is thermal drift — a phenomenon where the amplifier’s input offset voltage varies over time and with temperature fluctuation. Operational Amplifiers (Op-Amps) are ...

In this lab we introduce the operational amplifier (op amp), an active circuit that is designed with certain characteristics (high input resistance, low output resistance, and a large differential ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

Who is involved with simulating op-amp design and developing their datasheets? Clarifications on sometimes obtuse amplifier specifications. Pitfalls to avoid when interpreting ac specs. What to watch ...
