If you are driving long cables, a "low" power amp input impedance, a low value pot for volume control or some other circumstance that needs the ability to drive 600 ohm loads with a high level of Supersonic V1 - Dual Op Amp SUPERSONIC V2 - Dual Op Amp Sound Character - The sound is very neutral with stunning dynamics, openness, presence and detail. Personally, the NJM4580D sounds better. The NE5532 is used everywhere as its sound profile is designed to catch people's attention. Forums. 2k, and remember that you'll need to NE5532 vs NE5534. It needs to be well decoupled so the PCB must have caps from + and - to GND close to the opamps. Joined 2008. 2014-06-12 6:06 pm #1 2014-06-12 6:06 pm #1 Hello. Cancel; 0 Diego Melendez over 9 years ago. I replaced the OPA2134 in my latest Bruce Heran design phono stage build with an NE5532 and lo and behold that phono stage now possesses a similar 'cool' sound in large part. I've tried replacing it with a number of opamp (OPA2314,LT1057,LT1364,OP275,OPA2604,LME49860). 7 nV/Sqrt[Hz] vs NE5532 with 5 nV/Sqrt[Hz]. MUSES8820 is the best, IMHO. Total Price:USD 7. I have philips cd 210 player using lm833 opamp. 3V inside of each supply. 5V to Wide Operating Voltage Range V ±18 nV/√Hz Equivalent Noise (Frequency = 1kHz) 1. The lm4562 is practically a lower voltage version of the lme49860 opamp. 00 It does come supplied with the workhorse NE5532 which is a solid choice and rather inexpensive these days (~$0. Posts: 4,116 LME49860 is a candidate and it is also bipolar. I'm also waiting on 2 boards of a much simpler NE5532 pre amp and 1 phono section. OPA2134. LM4562 sounds much more detailed including middle and treble sections too. The OP1656 is the exact &lt;unk&gt;1 เครื่องขยายเสียงคู่ Flagship Edition JRC Pyro อัพเกรด NE5532 OPA2604 LME49860 จาก 3dymy Electronics Component Market. If the 5532 is ok to use at 17V will the slew rate make a difference considering it had the 4558 there in the 1st place. strangely its probably the most boring sounding one when paired with 400i but the best sounding with hd600 BTW, 49990 is a just a cherry Hi, I replace NE5532 for LME49860 ( my habit is to replace a bipolar chip for a bipolar one) with good results till now. ซื้อ2ลด5%; I have also tried LME49860 (TI/National), but it has too much bass into my taste, however might have use in car audio. Ne5532 Sounds like the sound was washed and polished witha high sheen. Now the NE5532's can be found for about $. +V CC = –V EE = 15V, V RIPPLE = 200mV PP, R L = 2k NE5532 vs RC4558. Tested a lot of OP, including LME49720, OPA1612, OPA1642, MUSES8920 and MUSES8820. Offering unmatched clarity and detail, it's a top choice for audiophiles upgrading their equipment. Off the rear of my head the main concern would be BJT input vs JFET input. 00-3%. 2007-12-13 2:02 pm #1 2007-12-13 2:02 pm #1 Are there any performance issues that would lead you to prefer one over the other? and LME49860 for similar operating voltages. It comes with an NE5532. Am I correct? N. Start in 1 day(s) 23:13:31. 5 mA for the 33178, compared to about 8-10mA for the 5532. Will post again if I remember where they were. higher voltage. for "7 easy pieces" check out first pdf file in post #90 under 7 Easy Pieces . To the left we have some power supply circuits and input buffers made up of common NE5532 opamps. In case you receive the Burson Audio - Supreme Sound Opamp V5i with a manufacturing defect, please raise a return request within 7 days of delivery. ampslab. The NE5532 gets a bad rap from improper use in said circuits. 2020-10-05 10:39 pm #10 2020-10-05 10:39 pm Apparently the NE5532 in the 2U-1435 circuits serve another purpose than the IC106 and I wonder whether they should be different from the opamps in the IC106 position. maybe from here is the I'm recalling some noise vs. Wavewhipper. J. If you check out impedance plots of ferrite beads at RF frequencies, you'll find they top out at a few kohms in the best case, in the worst a few hundred ohms. 1µA vs 10pA). lme49860 ナショナル 2 回路入り ne5532 がありますがこの 5534 はさらにローノイズとなっています。 a バージョンはそのノイズをさらに max で規定して選別されています。音は 5532 よりいっそう清涼感がありパワフルです。と The LME49860 is even better and is good for +/- 22v max. 67 non-bulk pricing). My only complaint so far is the mounting holes are small (3mm) so I have to find some stand offs before I can mount this in a case. It uses the NE5532 Original file: https://www74.

It really depends on implementation. TI TPA3255 IC is buried under that gold color heatsink. frequency and distortion vs. Just did an A/B with 2 opamp buffers on my Hypex NC500 monoblocks, which I normally use with no buffer, as the dac has I have a Tektronix SG-505 Ultra low distortion oscillator, its based on either NE5534 or NE5532 chips can't remember exactly which one, anyway, many years ago when the LME series came out, I thought that if I used an LME49720 or LME49710 instead of the NE553x I would be able to get even lower distortion, I was wrong. You must trade-off the distortion and S/N ratio. 00009 % IMD Intermodulation distortion AV = 1, VOUT = 3VRMS Two-tone, 60Hz & 7kHz 4:1 0. These IC opamps significantly simplify the design process, production cost, and size of the equipment. AP2 does. 2014-03-24 9:42 pm #57 2014-03-24 9:42 pm #57 You won't hear dc, you need to measure the dc at amp output, if it's dc coupled that 18 mv could end up at almost a 1/2 Also consider the NE5532 and the later LM4562. Please consult other diy hobbyist, may be they can give u better options. g. The Burson V7 Classic is a drop-in replacement for many types of op amp: Dual AD823, AD823AN, AD8066, AD8620, AD712, AD827, C4570, JRC4556AD Hypersonic Dual Op Amp SUPERSONIC V2 - Dual Op Amp Sound Character - The sound is very neutral with stunning dynamics, openness, presence and detail. 5% in 2012, overall consumption in 2018 rose 3% from a year earlier to 3. Joined 2012. The V5i is a hybrid of sorts which includes both IC and discrete components, but is much smaller and should fit in virtually any Prior to using the V5i in my DAC-X6, I had used the OPA627 and the LME49860 which are quite popular opamps in the audio scene. 2) The LM358 has inputs that work at 0V and an output that goes very close to 0V, but the NE5532 has inputs that do not work when they go below 3V and has an output that goes down to only 1. Âm thanh của MUSES02 rất trong sáng, Interesting that solid-state "opamps" (SGA-HVA-1 & SK99 & SK25) are measuring extremely well and the well-known LME49860 (LME49720 and NE4562) is just a tad lower in performance. Sadly i've found controversial and opposite information, then i just The FETs follow the BJT inputs, it has much higher bias currents (10,000X)) than an FET input design (. Zoom. Maybe try the OPA2604, designer Thorsten Can i replace the LM358 with a NE5532 to lower the noise or hiss without replacing any other component? I'm powering one with 12v dc and the other one with 22v dc. The LME49860 (dual) however can operate from 36V supplies Can someone tell me what a better drop in replacement for the NE5532 might be? I got a DAC kit from China for really cheap and am putting it together. The LM4562/LME49720/LME49860 family is opinion far away better than the NEC C4570C. The LME49860 (dual) however can operate from 36V supplies with a 44V maximum. The most popular are these op amps which have found their way into a lot of high-end BRUTE FORCE ONE - Dual Op-Amp Ultimate 8 High End Parallel Op Amps making one Brute Force One. TL072 have low current output capability. Over this supply range the LME49860 maintains excellent common-mode rejection, power supply rejection, and low input bias current. 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. 5 nV/sqrt(Hz) of input noise VS 5 nV/sqrt(Hz) of NE5532 (NE5534 is quieter but I need a dual chip). 0V. lehtokj. I know that they could be single versions of any corresponding opamp, but that would require changing of the pin positions. Jump to Latest L. 19 . I know there are better op amps, but they are not available here, so these are my only 2 options: LM833 or NE5532 Based on data sheet info LM833 has 4. ti. I am very aware that this is a controversial area but even though NE5532 measurements are best why would one even think of buying discrete built opamps etc ? Let's just call it flavour. New posts Search forums. BurrBrowns sound like the sound was pampered and layed to rest while having a nice sleep NE5532 incoporates BJT circuitry inside, but if u wish to go something with FET circuits inside AD825 is the best choice. cbdb. This video title is; 2Which OpAmp is Better for 20W Class A Amplifier - OPA2604 vs NE553 The GBW of the NE5532 is 10MHz, and there are no microwave capacitors on either the TPA3255evm nor the Aiyima board. 00005 % GBWP Gain bandwidth product 45 55 MHz SR Slew rate ±15 ±20 V/μs FPBW Full power bandwidth VOUT = 1VP-P, –3dB referenced to output magnitude at f = 1kHz 10 MHz ts Settling time AV = –1 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. 37 for 1pc) - 48960 (USD4.
