OPA2134 is more stable, as it is not too fast for Audio. LM308, pretty much only applicable for the rat, reams of discussion on this out there, it's about its speed and bandwidth, it's crappyness turns out to be a bit desirable (to most but not all people). ah so much other untested opa's 1678 still on my list ina1620. the ne5532 looks a bit harder, narrower and more direct, the other two a bit more relaxed and Products Precision op amps (Vos<1mV) INA1620 — High-fidelity audio operational amplifier with integrated thin-film resistors and EMI filtering OPA130 — Single, 1-MHz, 20-pA bias current, 530-µA power, FET operational amplifier OPA131 — Single, 4-MHz, 50-pA bias current, 750-µA power, FET operational amplifier OPA140 — Single-channel, 11-MHz, low-noise 36-V JFET precision operational 出力電流もopa1642やopa2134より大きくなっています。 重ための負荷でも歪みの増加は極少でしたので、個人的には気持ち悪い使い方になりますが オペアンプの出力に負荷を直接ぶらさげても使える場面が結構あるように思います。 Jul 25, 2016 · So for a low cost the LM4562 or OPA2134. I have terribly damaged my Sound Blaster X-FI with so many op amp changes. 6 Specifications. May 19, 2017 · Joined 2006. TI’s OPA1678 is a Low distortion (-120 dB), low noise (4. I find the AD823 very grainy and harsh, even when used in front of a buffer. It's not 100% clear, but from what I have read, the OPA1642 uses dielectric isolation to avoid the typical problems of common mode signal induced, input pair drain-to-substrate capacitance modulation that can cause relatively large amounts of Dec 4, 2017 · Part Number: OPA1642 Other Parts Discussed in Thread: DIP-ADAPTER-EVM, OPA2134, RC4558, TL072. 8ma quiescent current per channel - half as much as OPA2134,OPA1656 is the best boise performer now, but there many different purposes with different requirements. I have tried muse02, muse 8920 didnt feel they were worth the hype or price. Type 812 flour. Bauhausler said: Howdy. Other Parts Discussed in Thread: OPA1652. 8610/20 are used in many high end amps. Dec 27, 2019 · Dec 27, 2019. Personally this is my favourite op-amp. nognow. I'm not sure if there will be a new version in the near future, but Digikey is completely out of stock of all forms of the OPA2314 op-amp. but the difference between opa2604 and LME49720 is much smaller than the difference between these two compared to the original ne5532. So I can use any one of these ( one at a time !). We would like to show you a description here but the site won’t allow us. The OPA1641 (single), OPA1642 (dual), and OPA1644 (quad) series are JFET-input, ultralow distortion, low-noise operational amplifiers fully specified for audio applications. Jan 7, 2002 · Joined 2001. Comparing the two, to the slightest extend, the opa627 sounds smoother, softer, lighter, calmer. +Gain Bandwidth. (Normally one would probably point to LM4562 as being the best compromise, but I think the Quiescent Current of 10mA is very high) OPA1656 has even lover distortion. NE5532 could work in higher supply voltage,for example,+/- 22V. ) He talked to me about OPA1611's versus OPA134's as well as the OPA1612's versus OPA2134's. amplitude and THD+N vs. The OPA1602 and OPA1604 bipolar-input operational amplifiers achieve very low 2. Mar 30, 2023 · The main difference between LM4562 and OPA2134 amps is some key features in their product descriptions. Likes. Forward midrange (but not as bad when OPA2134 on input stage) Less soundstage (but not as narrow as when OPA2134 in input stage) The sound is completely mixed. de dr ow sh yv tr ph td od qz
