3 sty 2012 · newbie here. been reading through the forums about Op-amp ugrades and i had my first try a couple of days ago. i used LM4562 as the upgrade. i have an old 2-way active crossover lying around, when i opened it up i found 10 op-amps: 3 op-amps (2 ba4560, 1 ba4558) in the input section 2 op-amps (2 ba4558) in the filter section
10 paź 2020 · For me its clear evidence that LM4562 is a very good op amp. I have also tried opa1642, 1612 and 2134, but they are all slightly inferior to lm4562 soundwise in Aiyima a04.
30 sty 2004 · The LME49720 output stage is optimized for supply voltages under +-17 volts. The LME49860 is optimized for +-14.5 to 22 volts. The LM4562 is similar to the LME49720 except it's in a metal case and has better heat dissipation and drives 600 ohms effortlessly.
14 kwi 2021 · With my curious nature of experimenting for upgrades, I tried opamp jumping with 2 reputable opamp chips without changing the factory circuit. Of course, I kept a close eye at the datasheets to make sure no absolute maxima were crossed. The first opamp was an LM4562 from National. Not the T.I. variant.
15 mar 2014 · My experience with "upgrading" op amps and capacitors has thus far been to degrade the sound. Might be best to leave these newer models alone. - as to a favourite op amp, mine would be the LM4562.
The LM4562 is designed for high slew rate, low noise and high output for systems needing +/-2.5 to +/-17V functionality. The pin out is the TI standard to quickly upgrade existing boards. This series is for applications such as high quality audio amplification, multi-media, imaging, line drivers/receivers and active filters.
The LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/√ Hz ) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications.
