App note from Apex Microtechnology on determining the full bandwidth of high power op amp. Link here (PDF) Getting the highest bandwidth out of a Power Op Amp is one of the most common challenges in highpower analog. Whether you’re outputting a 3 MHz sinewave into a semiconductor during testing, or getting the sharpest corners […]

25 watt hybrid EL84 tube amp
Ray Ring from Circuit Salad has published a new build, 25 watt hybrid EL84 tube amp: This is my new hybrid guitar tube amp which utilizes a solid-state input stage, DSP reverb, and solid-state phase splitter. Only the push pull, class AB output stage utilizes tubes, namely two EL84’s run at 390 volts with cathode bias. […]
App note: Slew rate verification for wideband amplifiers
Linear Slew rate verification for wideband amplifiers from Linear, an app note (PDF) : Slew rate defines an amplifier’s maximum rate of output excursion. This specification sets limits on undistorted bandwidth, an important capability in A/D driver applications. Slew rate also influences achievable performance in D/A output stages, filters, video amplification and data acquisition. Because of its importance, amplifier slew […]
Decompensated operational amplifiers
“This video by Analog Devices’ Matt Duff explains why a few operational amplifiers (op amps) on the market are not stable at low gains, but are stable at higher gains.”
