7 sty 2021 · We have now SINAD = 88dB at 5W/4ohm/1kHz and @24kHz BW. So considering NE5532, LM4562 and OPA2134, OPA2134 gives best measured results in AIYIMA A07. And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here.
19 maj 2017 · By most standards the LM4562 is a superior op-amp to the NE5532. I'm still (perhaps irrationally) fond of the OPA604, maybe because some equipment I really like used it. That's a FET input op-amp though.
23 lut 2019 · 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.
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.
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.
29 lut 2008 · I've read about the 'Sondigo vs. X-fi Prelude' comparison a few threads down and I basically concluded from that the AD8620 might be considered better than the default LM4562. That said, a few people consder the OPA637 an 'upgrade' from the AD8620.
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.
