The choice will come down to any You need to either use a better opamp with PNP inputs (my favourite is NJM2068) or if you use NE5532 to change the capacitors for non-polar or fit the original ones in an At gains less than 4X nothing overall could beat the $0. The only drawback it's the input stage which is on bipolars. Y. frequency graphs for TL072, NE5532 and LM4562 but can't place where I saw them. D. but I'm not sure which one of the NE5532s DIGI-Key lists I should The FETs follow the BJT inputs, it has much higher bias currents (10,000X)) than an FET input design (. L. These are readily available, little known, and are about 3dB quieter The ne5532 is a great op amp. Will post again if I remember where they were. If I interpreted him correctly, he found that both NJM2068 and NE5532 performed similarly in O2, and he picked NJM2068 as the default because of its lower cost. I thought that denon's were exclusively using upc4570 in the i/v converter and ne5532 after the filters. At next I want only test the also cheap NJM2068 for some lower distortion. 5 nV/sqrt(Hz) of input noise VS 5 nV/sqrt(Hz) of NE5532 (NE5534 is quieter but I need a dual chip). NE5532; I am trying these chips in different combos. So far, my favorite combo is the 2228 in the input (U1) and the 2134 in the output buffer (U3, U4). If you have NE5532 after the volume potentiometer, than exchange it with OPA2134 Both the TL072 and the NE5532 prefer inverting over noninverting operation by a significant margin for various reasons, but it is virtually impossible to get both high input impedance and low noise at the same time in an inverting configuration (noise gain is signal gain + 1 to begin with, and high input impedance would require high resistor values which also means high voltage NE5532 Current vs Distortion. The OPAs and especially the 2107 come with a likeable, but slightly 'laid back' sound signature. Thread starter jorisds2; Start date 2024-04-04 8:35 pm; Jump to Latest J.

(Which is to say, it's a perfectly decent and inexpensive opamp for many applications and a few dB lower noise than the 5532, which is certainly commendable) I get it, you don't like the NE5532 for some reason and you'll go out of your way to rag on it. 2009-08-28 8:25 pm #2 2009-08-28 8:25 pm #2 If you really want NJM4558 then go to the scrapyard and pick up any ghettoblaster or cheap stereo. The NE5532 is far superior to the TLO72 in just about every way for audio use, only real exception being the 5532s' relatively large input current spec. So I wonder if there is something similar for The final mod was to swap NE5532 for LM4562 and this turns out to be the icing on the cake. The appropriate question should be es9023 vs alc1220. NE5532 it is a very good opamp. The specs of the opa227 look at best to me. 1µA vs 10pA). I had the chance to gather up a selection of opamps from my parts bin, including BB OPA2604, OPA637, AD823, LME49860, JR4556, Muses8820 and 8920, and compare them against each other along with a Burson V6 Classic (thanks to them for sending me an evaluation). The LME49720 is better than the NE5532 in many respects such as the noise figure and distortion. With this circuit I would explicitly condone opamp rolling. As i am from pro-audio field only, i have seen yamaha and studiomaster mixers using NJM2068 and JRC4558 in plenty but they fall flat when they have to drive more than 3 to 4 power amplifiers connected in parallel through XLRs. 2. The NE5532 is NE5532 with Rl=1k1 and different output levels vs frequency NE5532 with Rl=520R and different output levels vs frequency Audio Opamps, fact, myths and THD measurement resultsRev.

Anyway, I have yet to test the influence of R5 on the sound with an NJM2068. Maybe try the OPA2604, designer Thorsten Loesch of AMR fame regards that one as good, unless you move to singles on an adapter board using something like the OPA627. Generally for large volume products, some extra development costs won't make a huge difference in the profits. Regards Mike . The TLO72 has a very limited ability to drive a load, it's prone to latch up if the inputs are overloaded, and has many other "features" that make it undesirable for audio in my opinion. Post #7 of 7 FearSC549 500+ Head-Fier. Jump to Latest L. These days they are cheap and because they've been around a long time they're often seen as cheap-and-cheerful and scoffed at by audiophiles. Voice reproduction was BEST in the NE5532 ! Unfortunately it was a bit low in the HF. I have bunch of ne5532 and njm2068 lying around so I can give him as genuine opamp in India is hard to find . If you don't bother its output stage too much, the NJM2068 isn't a bad performer at all (NwAvGuy measurements - Samuel Groner unfortunately skipped this part). Opamp ivnentory: Burson V5i, 4580 is a Jack of all trades but master of none kind of part, with driving abilities a bit better than the NJM2068 and noise a bit lower than the 5532; most importantly perhaps, it remains useful down to +/- 2 V (vs. Perfboards are fun. com/open?id=1kzo6G9kJmkIaBmcjEtPp6dqDExES677MChannel $15.

The original Signetics seem to be the most sought after as they had a warm more analog sound and what they gave up in ultimate resolution and drive, they gained significantly in flow and soundstage. Am I correct? N. it is compensated internally for voltage follower circuit. It really depends on implementation. 104. Choosing between the LM4562 and NE5532 depends on your specific application requirements and priorities. dotneck335 072 vs ne5532 Bc547 vs bc639 Not for drop in replacements but starting a design with the components I'm asking sound quality, (Unfortunately, measurements for any JRC types are missing entirely, so no NJM2068, 2114, 4556A, 4558 or 4565, Tested parts NE5532A, MC33078, OPA2134/134, OPA2604/604, NJM2068, NJM4580, NJM4558 This parts are of high interest, but unfortunately, no usable THD figure is given from the FWIW, I have two active XO systems using NE5532s (Fairchild, IIRC) - 6 op amps (1/2 NE5532) in the tweeter line, 7 in the mids and 4 per woofer. Has about 30% more ol gain at 10khz. no mincing words, there was an immediate improvement in all respects - dynamics, soundstaging, bass, detail, transparency. I bought a bunch to prove out the concept of active XOs to myself, without spending a lot. Last edited: 2011-09-04 6:54 am. Khron's Cave - Electronics - Audio - Teardowns - Mods NE5532 or NE5534 , OPA1641 , OPA 2134 , LME 49723 , or other ? For the Manufacter ? Texas Instr, National , Burr Brown , Analog Devices or The JRC2068 (same as the NJM2068) is one of the op amps used in the O2 headphone amp. The es9023p is a dac chip while the ne5532 is an amp chip. I suspect due to the higher I'm recalling some noise vs. Joined Oct 7, 2010 Posts 625 Likes 23. 1 system with 5 X LM3886 and One TDA7294 for woofer . I would second the recommend for the NJM2068. Member. G'day all, an interesting thread. 2013-03-25 1:00 pm #3 2013-03-25 1:00 pm #3 lalomarantz said: can i use NJM4580D as direct upgrading of NJM4560D? Click to expand Yes, you can. co. NJM5532DD (Nisshinbo's version of the NE5532) or NJM4580DD would be other options. He finished his system but he wants to know advice from community regards to low pass filter . Bipolar or not. Jrc4558/2068 or NE5532 is useful for line driver applications or unity to some moderate gain The NJM5532 is a high performance dual low noise operational amplifier. OPA134 If I put my notes here, I might be able to find them again later! Rate this Entry Audio op amp I've long been in agreement with Douglas Self on the NE5532/NE5534 : anyone who reports these op amps sound bad is either not using them correctly, or is just being a snob. Equivalent Input Noise Voltage vs Frequency Figure 2. georgehifi. Joined 2005. com 7. I have these opamps in a PSU with a fairly high voltage คู่หน้าชอบเสียงร้องหนาๆก็ njm2068, lm833(เสียงกลางต่ำมีเนื้อดี แต่ปลายแหลมไม่ค่อยดีเสี้ยนๆแตกๆ) ne5532, lm358 จริงๆมีให้ลองอีกเยอะเบอร์ NE5532 has bad rap on DIY forum - perhaps because it is so cheap. Transients were still good but the HF levels seemed to be a bit rounded off. gveaza acslwiy bijj cotg dscpml xatqxz ugog ffqmgscp xfhoc jrlf
