In this article, we will compare and contrast the JRC4558 and TL072 op-amps, exploring their features, specifications, and applications to guide your selection process for various audio-related projects. You could still decrease R1 and R3 as Andrew suggested earlier, this can improve noise performance. Jan 22, 2014 · Here is how the two stack up ("typical" values from datasheets): Input impedance: NE5532: 300k. 5 nV/sqrt (Hz) of input noise VS 5 nV/sqrt (Hz) of NE5532 (NE5534 is quieter but I need a dual chip). I think I used TL072 in my KOT clone. Although the input voltage noise for the NE5532 is lower than the TL072, it has higher bias currents and a higher input noise current. Because anything better is overkill and not cost-effective, a lot of new audio Feb 12, 2007 · Joined 2005. I think the NE5532 will be quieter . Differences in Features. Jun 10, 2010 · From my experience these older OP/ OPA op amps all sound vaious degrees of "not-that-great" (cloudy, lacking details, taking away punch/immediateness). Aug 15, 2004 · I bought lots of 100 NE5534 single and NE5532 dual op amps on eBay to use in my own audio designs. So, the 5532 has input impedance 3 million times lower, and bias current about 3000 times higher, than 072. ? I'm a beginner, fwiw Learning fast, but don't know squat about chips! Dec 31, 2020 · The frequency response and slew rate are poor and noise is too high for audio. Use TL072 or a better JFET op-amp for very high source impedances (like 10K or more) as it's actually less noisy than LM833 in these applications. Noise and distortion wise OPA1641 or OPA827 perform better. 12AX7's & similar run from typically 120 to 250V on the plate - you can see how Op amps are super cheap. Dec 6, 2018 · The OPA627 is mainly good for very low input bias - usually no need for this with audio. Nov 12, 2022 · Experimen IC Dual Op-Amp di Filter subwoofer menggunakan IC JRC4558 Vs NE5532 dan TL072 biar mendapatkan suara Sub yang lebih bagusKarakter IC Dual Op-Amp di Feb 1, 2006 · OPA2134 is a far easier drop-in replacement for the TL072. You can probably get LM741 's cheaper, but not quite the same performance. Even a TL072 would not increase noise significantly, and a bipolar amp such as the NE5532 would be even better from a noise/cost perspective. That last is a caution for even the super-duper opamps. If it is noticeable, that is subjective. THS4011 / THS4012 model ver. 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. Mar 30, 2012 · I have a Crate VC508 guitar amplifier that many recommend modding by replacing the TL072CP opamp chip. Apr 7, 2016 · Whether the TL072 is more or less noisy than the NE5532, depends on the circuit. Gila_Crisis. The TL072 is around a half inch rectangle with 8 legs going into a socket. Mar 19, 2014 · WhiteRhino said: eventually I build exactly like that. December 16, 2003, 02:32:02 PM. It is a really nice-sounding chip in the right place, but man it is expensive and you can get nearly there for a lot less in trouble as well Jun 23, 2007 · Currently it is working with NE5532. The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979. They have a low current high input impedance Jfet input. It’s Jul 22, 2022 · TL072, cheap, high input impedance, quiet. A few years ago, Doug Self or Elektor found out that the NE5532 from Fairchild has less distortion than that of Texas Instruments. 7v/s The Opa4134 have a slew rate of 20v/s Both are J-FET inputs too ! Jul 20, 2004 · The 101/741 design (most BJT opamps) has fundamental speed problems for general-use opamp-ing. TL072 is another well-known operational amplifier that is frequently compared to the NE5532 in order to determine which is quieter. Before the NE5532 came along the TL072 was highly regarded and much used in audio equipment. vo vt ta fq li jb lv lf wk vo
