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 ...

Many technical documents have been written on noise analysis. Early on in my career I became obsessed with operational amplifier (op amp) noise. Subsequently, I published a series of application notes ...

Previously I discussed how to use a spreadsheet to visualize an op amp's Noise to help pick the lowest noise for any source resistance [1]. In this article we will use Texas Instruments capable SPICE ...

Why the fresh emphasis on low-noise amplification? Some of it is an issue of signal-to-noise ratio (SNR). Today, sensor voltages and device operating voltages are lower than they used to be, so noise ...
