I was just curious what people's thoughts were for that opamp, and if they had any other preferences in terms of quality? I've been using I have a fully parametric EQ design that I would like to build using OPA1642 op amps, because even with about 6 of them cascaded, I expect their noise and distortion to still Swapped the Op Amp in my cheap Pyle phono pre to a OPA2134 and am really impressed in the difference. It is worth trying. I am fond of the bass response and warm tone of the 2134 in my existing designs, but the new application uses phantom power which is limited to a total of 10mA for the complete circuit. lme49713 vs opa627 vs AD815 vs opa2134 vs opa1612 vs opa2836.

Theme - Light; The OPA2134 doesn't have a specific ground input, just a V+ and V-. Technical Forums. Most of my experience with the listed op amps is from dirt pedals anyway. If a person can hear a difference in electronic circuits, there are tests that can easily measure that difference. I personally have the DT 990 and have tested it with the OPA2134 and find it requires a power supply of around 8V+ for it to achieve volumes higher than what a desktop PC can deliver. I tested the opa2134 vs the ad712 that were stock. Haha, in fact, it makes you wonder if a "better" opamp will yield just as much (or more) improvements over Burson. It's nice because it comes in DIP and SOIC, works at video rates, and can handle +-12V. Measurewise there's not really a difference comparing If you have an electronic circuit design or repair question, we're good; but if this this a general question about electric motors, motor capacitors, fans, servos, actuators, generators, solenoids, electromagnets, using motor drivers, stepper I would recommend OPA2134 or OPA134 and if you have money the OPA627 or OPA637. Last batch of 50 I bought was direct less expensively through TI. I would like to have your opinions and suggestions on this. If all you need to do is power the op amp, hook 30V to V+, gnd to V-, and you're done - the op amp has no concept of gnd outside of V-, so it doesn't matter if it's 15V and -15V or 30V and 0V. The 0. Will it harm the rest of the amplifier? I do not know if you are interrested but i have a preamp using the AD8610 (Which is basicly the same as a AD8620) and compared to the OP275 (I know it is not the OPA134) the mid and highs are more smooth and more detailed. Digital 30 votes, 13 comments. Probably going to switch to a SMD-only +-5V video rate opamp sometime, though, and just regulate the voltage down, to match with LZX's newer design choices.

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. I was wondering how big difference there is between 2132 and 2134 as the first one is almost twice the price of 2134. Discrete is just bragging rights, stick to the tried & true ICs. If anything, it has a more 'neutral' sound than the (possibly slightly euphonic) OPA2134, but its performance is very reliable and dependable and of a very high standard, which possibly explains its long standing use in 'professional' audio gear. A discrete wouldn’t do anything outstanding since the implementation is limited. The OPA2134 is an op-amp not comparable to the TDA2822, so you cannot use the same circuit and swap out the IC. diyAudio Community diyAudio Store. Save yourself the $230/pair. OPA2134 and NE5532 both have power supply currents of about 4mA per channel, and the new OPA1656 is a great option, but you could also check out: OPA1642, OPA1678, OPA827, and the newer OPA828, or also Facebook X (Twitter) LinkedIn Reddit Pinterest Tumblr WhatsApp Email Link.
