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. Tony. In recent years I've been using the OPA2134 which is a bit better (Linkwitz uses it in all his analog active crossovers and EQ circuits). OPA2134 Vs NE5532. The 60 hz spike is back which has me wondering if FET inputs and EMI susceptibility go together (see the FET OPA2134 above): Posted: Wed May 19, 2010 9:09 pm Post subject: OPA2134 vs. Even though they are similar in design and outlook, some features differ, including total supply (max), GBW, Offset Voltage, IQ per channel, Architecture, etc. For example, Aol for the OPA1656 with a 600 ohm load will have a linear output swing that is 1. Opamps surveyed: BJT input types The rest of this chapter looks at some opamp types and examines their performance, with the 5532 the usual basis for comparison. If I have any inspiration, I'll post it. 4kHz bandwidth Here we see that the LM4562, LM833, LM49720 and OPA2134 all have the same level of performance with the NJM2742 having the worst performance of the bunch and the LT1352 being just slightly worse. Harga IC Op-Amp LM741 DIP 8 Kaki UA741 UA741CP UA741CP Operational Single. I expected much better performance from the OPA2134, but did not perceive a difference. I've used both extensively back in the 1980's and 90's. 1. When the original OP is Bipolar(like NE5532 etc) we can most always replace with FET or another similar Bipolar OP. Can anyone really tell the difference between the different IC’s when built into a pedal and cranked Oct 8, 2017 · As noted above, low values become susceptible to stray capacitance and high values may cause excessive opamp loading. Jan 27, 2009 · Building a Marshall Blues breaker with board from GGG. 15V/us), noise rejection (120db vs 70-80db), lower offset, much closer to rail outputs, etc. Rp920. Admittedly, the Noise is a bit higher than the 5532 (about 6db worse) but similar to the OPA604 and OPA134 Op-Amps. I tested the RC4558, RC4580, TL072, NE5532, MC1458S, OP275, OPA2604, and OPA2134. I was reading de datasheet of the TL074, and I found that it's slew rate is 13v/s, pretty good if you compare to a poor RC4558 that is 1. The OPA164x family of operational amplifiers combine an ultra low noise JFET input stage with a rail-to-rail output stage to provide high overall performance in audio applications. Op amps are super cheap. 首先说双运放，玩过的有：JRC4558、NE5532、CA3240、TL082、TL072、NJM2114、LF353、LM833、MC33078、NE5535、AD8620、AD827、AD828、AD712 Mar 5, 2007 · LM4562 -- not by a very large margin ! 2. Jaycar $8. I've been using TL072,NE5532 & OPA2134 exclusively in most of my design projects,& the improvement from TL072 to Feb 12, 2007 · All of these come in the DIP package. It’s nearly 12 dB worse than the NJM part which is fairly huge—especially considering the TL072 is more expensive (about $0. Oct 21, 2018 · Zachęcony poprawą brzmienia jednego ze swoich urządzeń postanowiłem wymienić wzmacniacz operacyjny na lepszy. I'd also decrease the input impedance 100k resistor to some like 22-33k and increase the coupling cap as required. Jul 10, 2015 · Untuk pengganti ic JRC4558 yang lebih baik dan mudah didapat adalah ic TL072. 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. Tapi dibanding JRC4558, ic TL072 mempunyai performa lebih baik. Was wondering if we should use all OP275's for the 1101 input modules. The TL072, TL072A, and TL072B are high speed JFET input dual operational amplifiers incorporating well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. tl072 is faster and better suited for higher input/output voltages. So I was right the first time In the second tests, everything is TL072 anyway. Perfect for 9V or 12V battery powered kit. How to choose between lm4562 vs ne5532. I'd like to find a 3rd choice for critical/precision DC circuits e. Choosing between the LM4562 and NE5532 depends on your specific application requirements and priorities. Ic TL072 mempunyai karakter nada tinggi atau treble bagus dan lebih ciiss, cuma nada bass agak jeduk, kurang empuk. OPA2134 is more used and more liked, than almost any other JFET op ( Maybe still TL072 is most used, but it is far from OPA2134 in quality ) ----- OPA2134 is probably the most used DIY Audio op, all categories. Mar 21, 2017 · OP275. Likewise, resistors values should be between 2. TL072: 65pA. Lower values can be used if the opamps can drive low impedances with minimal distortion (e. Probably, but in the equipment I have tested this the supply is about 100VA 30. Mar 13, 2023 · 2023-03-13 11:51 pm. So in the first tests, it is the OPA2134 which is acting as the comparator, and handling the input signal, and acting as the integrator. Jun 9, 2015 · I never really liked the TL072 but the LF353 was great. THD + Noise at 3 V rms is a low 0. All were new parts. Indeed, 2132 and 2227 are very similar, and I guess 2134=2132. 8 - LF353N. 4mA, respectively. It is commonly used as a modern alternative in audio applications where a Fet Input op-amp is required. Improved battery life: my A27 batteries are lasting only about 2 hours. 3 - unknown, the markings have been removed. these are just examples. The output os capable of driving 600 Ohm loads to 10 V rms while maintaining low distortion. Sep 20, 2011 · So with the higher power, the more heat it will generate. 4mA typ per amplifer but noise is higher at 18nV / rt Hz than the OPA2134's 8nV / rt Hz although lower than the 062's 42 nV / rt Hz ( with it's 200uA typ per amplifer Icc ).
