Apr 21, 2019 · SparkOS Discrete Op-amps SS3601 and SS3602 with comparisons to Ne5532/5534, Muses02, Burson v6 Classic, and Burson v6 Vivid op amps Aug 22, 2007 · Yes, the noise of the NE5532 and the LM4562 is equal at 3KΩ source impedance; below that, the 4562 is better, above that, the 5534 is quieter. You should be able to find single-to-dual DIP8 adapters for mounting 2xAD797 on a DIP8 socket. LM4562 -- not by a very large margin ! 2. But I noticed an odd op-amp decoupling in the Aiyima. They have, however, higher current noise and cost ten times as much. ••• Oct 31, 2017 · Zeptobars has full-size images of this real (left, obviously) and fake (right, double-obviously) NE5532 opamp – the left image is a genuine TI-brand IC and the right image is sold as “Ti” at approximately 1/20th the cost of the real deal component: We have spotted yet another real/fake pair of very common microchip. The soundstage somehow not as large as the OPA1642, but it is still in the good level of soundstage presentation. Mar 5, 2007 · LM4562 vs TL072 and NE5532 .
