Но это не значит что её надо на вход УК тыкать, сдуру можно и хрен поломать. Тыб Алекс второй проверил бы, а то может уже сломал?
Op Amp Measurements
INTRO: In last week’s Op Amps: Myths & Facts article I covered the background for op amps, why they’re important, and some common audiophi...
Discrete OP-Amp vs. Integrated OP-Amp include discret Buffer - e. g. AD797/844+IRF610
The threads "Discrete OP-Amp vs. Integrated OP-Amp without Buffer" are here: IC's vs Discretes Discrete opamp vs regular op amps Descrete jFET versus IC op-amp quality similar threads are here (integrated OP-Amp): AD825 module from LC Audio How good are the AD825 opamp for a TDA1541 dac IV...

LM386 THD and Noise measurements
I recently purchased a new piece of test equipment; a QuantAsylum QA400 Audio Analyzer. The specs of this unit get close to high-priced audio analyzers from Keysight and Audio Precision. For $200 U…

Big test of DIP dual op-amps for audio: LM4562, NE5532, OPA2134, TL072 and LM1458
There are questions if it matters which type of op-amp is used in the audio amplifier and my answer is that it depends on circuit schematics and op-amp parameters. Some of those parameters are obvious from datasheets, but others may be quite hidden and not clear from the first view. For the test...

как так?
что, все дураки, один неуло умный?
единственное измерение, сравнимое с неуло это топовые оу op1612

Nested feedback/ composite amplifier opamp requirements(unexplained results)
Hi everyone. Recently, I have been doing a composite amplifier with tpa6120a2. It's a great chip and i have had pretty good result so far. However these is something I can't explain so far. I have had a chance to measure the distortion of the original jds el amp and did modification with...

Как у неуло получается с древним 544 получить результаты как с самыми новыми топовыми оу?
