Opa1612 vs opa2134 vs opa21. jokan Addicted to Fun and Learning. OPA2134 and NE5532 both have power supply currents of about 4mA per channel, and have been widely adopted in the market (understatement). Opa2134 is a very good opamp. LM4562 is similar to I would recommend OPA2134 or OPA134 and if you have money the OPA627 or OPA637. I would recommend OPA2134 or OPA134 and if you have money the OPA627 or OPA637. The second time I did test with opa1656 and opa1612. The AD826 seems to be smoother than the OPA in the voice range. ナチュラルビューティー。脚色がほとんどない、いわば素肌美人である。音の抜けが良く、ジャンルを問わず使える感じ。超高域の解放感はもう一歩か。でも、充分リファレンス用途までいける。単価も音質の割に破格と言っていいだろう。 I tested the opa2134 vs the ad712 that were stock. Other Parts Discussed in Thread: OPA2134, OPA2604. over 6 years ago. Goes to show you how good it really is. Try them and see for yourself. OPA2134 gain stage with voltage series feedback. Using hd600s and 400is to test them Ive compared the OPA1612 or OPA1656. 5 mA. gif Okay so I've been comparing the micro stack, ultra micro stack and the basic desktop amps. Anything other than these values and they're either fake or damaged (or both). He talked to me about OPA1611's versus OPA134's as well as the OPA1612's versus OPA2134's. Thread starter Acapella; Start date Sep 20, 2023; A. I can't really hear difference this time. If a FET-input amplifier is required for low bias current (such as for a phono preamp), you might consider the OPA1642 or OPA1678. 000015% at 1 kHz. Another way to say it: JFET OPamps like OPA2134 can Again, the OPA2134 is IMO a very good opamp but the Burson is just better. Pierre. Guru 140200 points Hi Pierre, the OPA1612 has a very low input voltage noise but at the same The LME49720 is pin for pin compatible for the OPA2134, the OPA's have the typical laid back Burr Brown sound. Since i couldnt find an opa2134, i just use tl072 and the likes for our projects I am just curious how opa2134's output performance. According to the TI datasheets OPA1612 has less noise than OPA1656. And opa1642 has a bit better soundstage I don't know why. 4. AD826 used instead of the the OPA2134. Thread starter pma; Start date Jan 7, 2021; Now they seems to have changed again to opa1612 in many places - maybe a suggestion to try ? I have tried ne5532, opa2604, lm4562 and opa1612 and I prefered LM 4562 in both Aiyima a07 and The OPA2134 is a low-noise, ultra-low-distortion operational amplifier designed specifically for audio applications. High and low extension is not only better but more controlled. Treble is extended without being sibilant or piercing. Smooth and natural. Other op amps you can try are AD823's but they can be a bit noisy when used at the inputs of a phono stage so I prefer them in the output stages. Two cases were evalutated – in a Hello, Wandelblu, Minon. The new national opamps are also there with extreme slew rate of 1900v/usec just like AD815. Acapella Member. One other very noteworthy difference is the Vivid has a strong attack, but loses a bit on the decay so sustain is better on the SS360x. Depending on the actual application circuit, there are alternatives with better noise performance. Originally Posted by mikeg88 /img/forum/go_quote. But now I have to replace them. Do you know why i obtained this issue with the new OPA1612? Thanks a lot. 1. That seemed like a reasonable target for the supply current of the OPA1656 as well. But $40-57 each. Super Contributor; Posts: 19833; Im interested in op amp rolling for my amp since its not expensive to try out and I was surprised to find a lot of variation between them, the amp has a very simple circuit so my results could be more siginificant than with other amps. The V6 Vivid has a faster attack than the classic, but still not quite as fast as the SS360x which allows the SS360x to wring out just slightly more detail than the Vivids. To deliver improved sound quality and speed for exceptional audio performance, a real FET input stage is included. The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range. . I just thought using two opa627, i will achieve 2134's audio quality. The main difference between OPAx132 and OPAx134 is in DC precision of the high grade of OPAx2132P/U and OPA2134 (e. Logged Zero999. hi i wanted to know if anybody have used the above opamps. The OPA1612 is used by Topping/SMSL and I believe Gustard is using it too and also in the Latest Topping Preamp that everyone is gossiping about. It's a killer OpAmp, and better suited to non-inverting buffer duties than the OPA1612/2211 . Reactions: jokan. When the original OP is Bipolar(like NE5532 etc) we can most always replace with FET or another similar Bipolar OP. If a bipolar-input amplifier can be used, then you might consider I found that these two ICs had similar parameter, but some difference: OPA2134: lower noise(8nv, 2604 is 10nv), lower distortion(0. But deep bass and transients seem more punchy in the OPA2134. Part Number: OPA1656 Other Parts Discussed in Thread: OPA2134, OPA2604 The OPA1656 is the industry’s lowest voltage noise high voltage CMOS on the market. OPA2134 is probably a good choice in general. But just the bass sounds a bit far away in comparison. Sep 20, 2023 #1 Hello together, i want to put one of the mentioned OP Amps in my amp. max Vos of 0. I'll look at it if you know of one amp using OPA1612 sounding audibly better than another amp using cheaper op amp in objective listening comparison. TL072 works most of the time but I almost always find a better substitute in dirt pedals. OPA1612 sounds better than any transistor preamp I've ever heard and better then my own 6N6P 2 case -no barrels hold- 36kg monster preamp with a 100% double blind test win rate. If the orginal OP is a FET (like TL072, OPA2134 etc) we may be careful sometimes NOT possible to replace with Bipolar (like NE5532 etc). . 00008%, 2604 is 0. 1-nV/√ Hz noise density with an ultralow distortion of 0. 5mV vs 2mV, respectively). So I can use any one of these ( one at a time !). Input buffer and I try to use a cheap component like NE5532P, no noise, with OPA2134 no noise with the OPA1612 a lot of noise. g. The OPA1656 is the industry’s lowest voltage noise high voltage CMOS on the market. The 49720 is more clinical IMO. Cancel; 0 kai klaas69 over 6 years ago. Can anyone suggest drop-in replacements to OPA2134? I'm looking for a natural, transparent sound vs colored. A quick snapshot of the OPA1656 So I just blew up 5 Burr Brown OPA2134 due to bad labelling on the PCB (Ok I was also supposed to be more careful). Low- and Mid-Frequency Test Signals for Evaluation of Room Modes // Measurements: ESS Hump revisited // Humpify -- apply "ESS hump"-style distortions to audio files. 3. Which of the two mentioned OP Amps (OPA1612 or OPA1656) is the better one, in a scientific point of view. In comparison OPA1612 and OPA2134 also have a similar Opa1612 is generally slightly light weighted but very balanced otherwise. 8 mA, for the OPA2134 typ. He talked to me about OPA1611's versus OPA134's as well as the OPA1612's versus OPA2134's. Bass is more textured but like the vocals, you hear the FX processing which sometimes slightly dilutes the attack and slam of the drums in some 7 mA quiescent current is typical of the OPA627, for the OPA2132 it should be typ. AIYIMA A07 TPA3255 Amplifier Measurements and Review - LM4562 (and OPA2134) option. 4 mA, max. Tone controls? DAC reconstruction filter? The better FET-input op-amps are expensive because they are laser-trimmed and prices can be crazy. opa2134. It appears that the OPA1611/2 have a lower noise voltage, wider bandwidth and higher slew rate than the OPA134 and OPA2134's. I know there are a lot of factors that set these apart, but I'm writing to OPA2134 is great for buffer and clean applications but I never liked it for overdrive/distortion. OPA2134 costs an arm and a leg. How are LME49860, LME49720 etc? Are they The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low 1. It offers exceptional performance in almost any audio application. 2. I plan to get the brown dog adapters and try the opa 627's soon. 6SL7 tube SRPP gain stage with voltage shunt feedback. 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). Don't let power supply current limitations get in the way of performance. And without mentioning every op amp in existence, I'll close with I yet have to find a circuit where an NE5532 is the best possible option. #1.

Prodigy 205 points. Yes sir. But $40-57 each Careful swapping in a higher bandwidth part, they can oscillate in "old" circuit designs and not all parts are unity-gain stable. Part Number: OPA1656. But that does not say anything about the SQ. They were ok, very neutral, until I bought AD708SQ. 0003%); OPA2604: high slew rate(25v/us, 2134 is 20V/us), high bandwidth(20M, 2134 is 8M) In Active Xover, there are input buffer, filter, output with gain changing. This, combined with the high output drive capabilities and good DC performance, makes it suitable for a wide opa1612 与 . In other words, OPAx132PA and OPAx132UA (standard grades) are equivalent to OPAx134, which does NOT have a high grade. Joined May 9, 2023 Messages 9 Likes 2. The OPA1612 is one of the best I’ve ever encountered, the LME 49720 are hard to beat at any price. Burson V5i-D, AD708SQ, stock (the preinstalled) OPA1612 Opamps vs Opamps: Stock Xduoo's OPA1612 vs AD708SQ vs Burson V5i-D: Stock opamps are sounding like you hear music from a room next door. (Opa2134 is not broken in at all, so it will most likely get better w/time) The base is much better from the 2134, but it does not seem to be as powerful on the output side, but could just be the break-in needed. ayvbm gxegbm pjjhg zruc ivumyucny hzo sdux gdcxo thzkf mrbjgz
