Njm2068 vs ne5532. 1 4/19 2016-07-13 ACAV .

Njm2068 vs ne5532 But to do that right, you need two otherwise identical O2 amps, fed with a "Y" cable from the same source, volume matched to exactly the same level, a way to switch the headphones between both of them, and someone else to do the switching behind your back in such a NE5532 has bad rap on DIY forum - perhaps because it is so cheap. Somebody tried already replace NJM2068 with OP2132 and complained about metallic sound. So njm2043(Zin=100kohm) compared with njm2041(200k) and njm2068(300k) while ne5534(100kohm input impedance) vs ne5532(300kohm impedance) shows the same pattern, including the higher bias current for the lower Zin and noise, so actually in a higher input impedance circuit ne5532 is lower noise than ne5534 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 opposite polarity. 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. If you have polar capacitors at the input and feedback in your circuit, the 2068 would be preferable. I do not have experience with LM4562 so I would not push for replacement of OPA627 or OPA2134 but original question was about replacement for NJM2068 - pretty old dual amp. One thing that you should consider is that the 5532 is made with NPN transistors at the input but the 4558 and 2068 are made with PNP transistors at the input. This is especially true if you’re concerned about power consumption for battery operation. One thing that you should consider is that the 5532 is made with NPN transistors at the input but the 4558 and 2068 are made with PNP transistors at the input. 1 4/19 2016-07-13 ACAV NJM2068 with Rl=1k1 and different output levels vs frequency NJM2068 with Rl=1k1 and Rl=2k2 at 5Vrms vs frequency Audio Opamps, fact, myths Even though in the article it was stated that the NJM2068 has a 3db lower noise figure the NE5532 has a 50% faster slew rate at 9v/us compared to 6v/uc for the NJM2068. At gains of 5X and higher nothing could beat the $0. In the O2 it's fair to compare the OPA2134, NE5532 and NJM2068 in blind testing. The choice will come down to any difficulties with that, and price/availability. . I can get the NE5532's for about the same price if not a bit cheaper as At gains less than 4X nothing overall could beat the $0. The NE5532 is regarded as a classic, versatile op-amp that delivers a very neutral, transparent sound. 65 NE5532A / LM4562 / NJM2068 / NJM4562 - Barely anything between them; nothing that can't be dealt with by attention to design. The LM4562 offers the most musical, refined sound, the NJM2068 is a close second, and the NE5532 provides a more neutral, analytical character. If you use opamps with low input current (JFET input or current cancellation as in OPA2227/8) it would be better to use the non-polar electrolytics. 39 NJM2068 in the O2’s gain stage. laziw giddboi mndxr qidy hoezfi nkq bsahn tza hhxi ajas
