Burson’s Soloist Stellar is a $1,500 Class-A headphone amplifier delivering up to 8W of power, a dedicated low-noise IEM stage, and upgradeable op-amps for demanding headphones and sensitive wired ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

Burson is also using a transistor-based amplification stage built around four Onsemi MJE15032 transistors per channel. Those ...

The OPA1602 and OPA1604 bipolar-input operational amplifiers achieve very low 2.5nV/√Hz noise density with an ultralow distortion of 0.00003% at 1kHz. The OPA1602 and OPA1604 series of op amps offer ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

I have fond memories of the original Aragon 4004 power amplifier from my days when I worked as a high-end audio salesman. That was in the late 1980s and the big 200 watt amp sold for a lot less money ...

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 ...
