Modern Op-Amp Distortion Tests: Part 2 — A Few More BJT Types and JFET Devices

Many new op-amp types have appeared in the last decade, and Douglas Self thought it was time to evaluate those for distortion performance. In Part 1 of his article, he measured BJT-input devices using a similar protocol for five different loads and testing for basic op-amp distortion in favorable circumstances. In this second article, the measurement of BJT types is concluded, and he moves the JFET types to the test bench.

Modern Op-Amp Distortion Tests: Part 1 - BJT-Input Devices

Douglas Self has been using a tried-and-true palette of op-amps in his designs. Because many new types have appeared in the last decade, he thought it was high time to evaluate those for distortion performance. In Part 1 of this article, he examines BJT-input devices using a similar protocol for five different loads and testing for basic op-amp distortion in favorable circumstances. FET input op-amps are investigated in Part 2.
