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 ...

Picking a low-noise op amp is easier than ever, yet somehow harder also. How can this be? Harder – Because there are so many devices to choose from and the noise data is not always presented in the ...

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 ...
