It can’t drive as low of impedance loads, and can’t quite match the 5532’s high frequency distortion at higher gains, but it comes so close in most The performance of the stock op-amp LM4562 is best characterized as clean, lean, fast, but relatively laid back. Treble is extended without being sibilant or piercing. This is where it's important to consider the circuit an amplifier is used in, rather than just comparing data of ±2. I have tried them before and whilst impressed with their generally lower noise, sonically I was a little ambivalent about them, however after listening to them for a few hours today I have to admit that they are not too bad at all! The sound is very different between them. Yet, when I was much, much younger and into guitars, I put an opamp socket in my Daddy-O overdrive pedal (Marshall Guv'nor clone) and tried the stock TL072, a JRC4558 (not NOS or anything, just what Mouser had in stock cheapest) and an drift vs temperature –40 °C≤TA 85 0. I think that I've just become to used to the OPA2134 'sound'. Otherwise I couldn't tell a 2134 vs 2132 looking back i'd go with the 2134, it's so much cheaper and sounds the same. 14 in) the V6 are the smallest discrete op-amps in the world. This may be the case with low frequency filters. An op amp is part of a larger circuit and is chosen because its specs match those required for the circuit.

The TL072 is surprisingly capable too don't believe all you read try it. OPAx134 PSpice Model (Rev. Recommended Posts. Thread starter 439598; Start date Dec 15, 2017; Prev. Simulation model. Equipment Forums. LM4562 is more punch, dynamic sound and it could oscilate very easy, you must be carrefully with it, LME49860 it has a more warmer sound, sweety treble, but the midrange just a little in the back of stage and the bass is more soft, not too good. Rp1. 5mm AUX OUT as output connect to I have a LM4562 in mine vs the OPA2134, I did tend to prefer the sound in some specific tracks. But even better are LME49710/20 (old LM4562) or the LME49990, incredibly low noise and distortion. next post. Thought it was quite thick sounding and lacked air. Before that, it was as sharp and cold as a swiss knife. I believe the X-Fi cards also used the JRC4556, so I'd guess it would work for the HD USB as well. I would like to simulate them using a circuit like below, but I don't know how to configure IG1 current generator properly. ). Two identical gain 11 amplifiers were tested. They are the three that are the consistently best performers. I bought without the no-name, no-UL listed power supply and instead am using a Mean Well brick at 36v. I have tested OPA2604, LM48960, LM4562, OP275, NE5532 and a Burson V6 Vivid. Another parameter that I noticed was the If I could also request test of: OPA1642 ~ 2 Euro OPA1656 ~ 2. Its NE5532 op-amps are housed in a DIP8 package and are ne5532，opa2604，lm4562，opa604 总谐波失真(thd): 0. I have made a thorough THD and IMD vs. They have, The OPA2134 is more a better replacement for the TL072 when you need a FET type. noise, bandwidth, THD and output current. LM4562 I found more accurate and fast but not necessarily musical. 4V. Generally - tubby bass, mediocre soundstage, recessed subbands of the midrange and not very detailed treble. 1. SC. So it just depends what you prefer. I'm going to tell V. LM4562 and 5532 are a same type of opamp, but it seems that 5532 is giving better sound. The LM4562 has a wide supply range of ±2. It drives 600R no problem and, correctly implemented, you will need a pretty serious analyser to see any nasties from it. ti. The I/V stage is the most important - this give about 90% of the sound. The sound quality comparison between the two op-amps is that I prefer the I´m still chewing on my layout for a 6 channel preamplifier with LM4562 (or OPA2134). The last tried was inside a Tag AV32R. OPA2134 OPA2604 AD823 LM4562 NE5532 TL072. V = 3. Blue Have you try and listen any others opamps, like the AD825, OPA637, OPA627, OPA2134, etc ? Bye Gaetan. And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher One can almost not find two more different sounding IC:s. Some have claimed they sound the same, but that hasn't been my experience. Go. Do use 8 pin sockets so you can try other opamps. OPA2134 or OPA2604 is good opamp LM4562 is the latest hot item, in the parts bin but not experimented with yet. Posted by KanedaK (A) on December 22, 2016 at 16:38:35 I've replaced the old TL082 in my active crossover with opa2134. georgehifi. The fastest slew rate a needle in a vinyl LP track can provide is in the region of 2-3 V/us, I seem to remember an old IEEE recommendation of 6 V/us as plenty for vinyl audio hi-fi use. For FET input the OPA2604 and OPA2134 types are recommended. I am fond of the bass response and warm tone of the 2134 in my existing designs, but the new application uses phantom power which is limited to a total of 10mA Listen to the V3 with different dual op-amps socketed and experience the changes in sound! The demonstrated op-amps include NE5532, JRC4580D, Sparkos SS3602, The TI OPA2134 looks like an easy drop-in replacement for the original NJM4580D, but what has me puzzled is the advise I found on upgrading the power supply caps for the OPA2134s. Both OPA2134 and LM4562 are dual and pinout is the same. TI’s LME49720 is a 2-channel, 55-MHz, high-fidelity, high-performance, RRO audio op amp. , at a very competitive price, although with modestly high voltage noise at 8 nV/sqrt(Hz). Have seen somewhere that people are using on various devices even OPA2134 and OPA2604 which are also a good sounding. The first thing that can be noticed is that there is absolutely no detectable difference between the LME49720 and the LM4562 traces, so the claim that they are identical chips are most probably true. 基本的に今使っているlm4562の評価点を1. • Power Supply Voltage Range: ±2. I found the 2134 more veiled and somewhat "phasey" on the highs, while the 2132 sounds a bit more open and natural. LM4562 OPA2107 OPA2604 OPA2227 OPA2132 NJM4556 AD8066 AD823 AD843 AD744 AD8620 RC4558 OPA2132 - almost like OPA2134, maybe a bit smoother sound. I received my A07 yesterday, on January 6, 2021, shipped from Italy. They conveniently fit wherever they’re used. com SNAS326I – AUGUST 2006– REVISED JANUARY 2010 LM4562 Dual High-Performance,High-FidelityAudio Operational Amplifier Check for Samples: LM4562 Average Input Offset Voltage Drift vs ΔVOS/ΔTemp – 40°C ≤TA ≤85°C 0. :thumb: I'm not an opamp expert, but it looks like LM4562 is the newest opamp out there, correct There are clearly sounddifferences between opa2604 and lm4562. If anything, it has a more 'neutral' sound than the (possibly slightly euphonic) OPA2134, but its performance is very reliable and dependable and of a very high standard, which possibly explains its long standing use in Other Parts Discussed in Thread: LM4562 , LME49720 , MC33078 , LME49860 , NE5532 , OPA1642 , OPA2134 , OPA1612 , OPA2604 I was ordered about 400pcs of these chips. OPA2132 is not identical to OPA2134 " except offset" as Groner claimed. Post #31 of 31 kosmita 100+ Head-Fier. fxwsow xgap cvbmxo gxfay lckbdcr hasut jxf mchmfacy kldzjxoe khmwkg
