19 maj 2017 · I have made headphone amps with good 'audio' FET input op amps wrapping 100 MHz DSL driver cfa op amps. the composite multiloop feedback linear stability is much easier to design with the output much faster than the input op amp.
29 lut 2008 · The LM4562 is a nice opamp and won alot of awards when it was released for the performance to price it is good. The AD8620,627,637 are in a different league then the 4562. The AD8620BR, is a very nice opamp and you should be very pleased with it.
7 sty 2021 · It seems paying a few more dollars for LM4562 op amp instead of NE5532 doesn't really make much sense. LM4562 may be slightly better, but the difference is not audible.
30 maj 2023 · The LM4562, known in audio circles as a game-changer, represents a pinnacle of operational amplifier design. In this in-depth exploration, we're going to plug into the heart of this chip, allowing readers to truly understand its brilliance and how it has reshaped the audio landscape.
23 lut 2019 · Jan 7, 2021. #1. AIYIMA A07 TPA3255 Amplifier Measurements LM4562 option. I received my A07 yesterday, on January 6, 2021, shipped from Italy. Purchased at Amazon.de and as stated on their website, it arrived without a power supply. I am testing the A07 with 2 different power supplies.
8 gru 2018 · The LM4562 is a completely unsuitable replacement for a J-FET op-amp. It's a BJT input op-amp with a high bias current of 72nA, compared to, 65pA typical, 20nA worst case, for a J-FET op-amp such the old TL072 and a 55MHz of GBWP could be far too fast for a circuit and layout designed for one with a GBWP of 3MHz.
13 sty 2024 · It seems like the best performing audio op-amp that still comes in a DIP package is the LM4562, so that is what I plan on using for the op amps. The preamplifier uses a high pass and low pass filter at the input to set the bandwidth, then an input buffer stage with parallel LM4562 op-amps.
