Oct 8, 2001 · Datasheet shows 9v/uSec for NE5532; but certainly not the BEST for phono amp application----about 5 db noisier than an LM4562/LME49720, but definitely less $$--about 1/3rd the cost. 調べてみましたが違いは分かりませんでした。. #1. Nov 26, 2017 · thanks for your tips! i have tested the opa2604 and the LME49720 compared to the ne5532. OPA1656 sounded worst, Muses 8920 sounded best. The OPA1632 delivers excellent audio quality, very low noise, large output voltage swing, and high current drive. In my opinion, the Aiyima a04 with lm4562 sounds a little better than a07 with the stock ne5532. Which is fine. Sound is more "color", and "massive". Probably reached the "good enough" range. Unlikely. Note the size difference between the two units. strangely its probably the most boring sounding one when paired with 400i but the best sounding with hd600. Thanks in advance. A cost saving alternative is the OPA1678 which is my new favourite OpAmp R2R output, costs almost the same as the 5532, similar performance, May 30, 2007 · YFW said: I suggest you should condider the requirement of the circuit first.

Jun 7, 2016 · Easy & Effective. It's a VERY good bipolar junction opamp with incredible specs. try modding with better FET input opamp, like OPA2107 or OPA2111. The Aiyima a04 with lm4562 is dead quiet - no hiss at all. If there are more complicated parts (especially active parts) in the FB path, a faster OP can be a problem. I'm not surprised the NJM4556 came out on top. 2010-06-10 8:32 am. Jul 4, 2009 · What I am scared of is instability, I'm not sure if the P2 has bypass caps for the NE5532, and not exactly sure how bypass caps work with dip-8 sockets. ゲーム制作業界への供給が中心ではあったものの、気が付くとレコーディングスタジオやマスタリングスタジオまで機材供給をするようになっていた。. 4mA/channel) Oct 2, 2021 · Also here a little more information. Similar to the size of a typical DIP8 opamp, the V5i is the easiest plug-in upgrade for any audio project. On distortion front though, the SparkOS has fair bit higher distortion (> 10 dB). The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979. And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here. B. The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600 mV with a 2-kΩ load, which increases headroom and maximizes Feb 21, 2010 · The 5532 are generic opamps that have been used in a great deal of audio gear over the years. Since I am not interested in the V6 Vivid Dual that it comes with. You can see this in the specs for the tpa3251 and tpa3255 used. The LM49860 is much clearer and cleaner then the 5532 so you might want to keep that in mind. Jan 6, 2010 · Member. 10MHz) noise (4. Joined 2009. It excels in premium audio equipment like Dec 10, 2021 · DIY Audio. Mega File Upload - hfe_technics_sl-pg440a_service. The Burson V5 (left) and V5i (right) in their packaging. Share Nov 12, 2010 at 6:10 PM Post #8 of 20 Jul 25, 2016 · So for a low cost the LM4562 or OPA2134. ••• 而中高频又和opa1612+1612几无差别,很可惜的是自己只买了一对,没法直接瞬切,但差别肯定是非常微弱的。 打分:95分(后面自己又试了1642+1642的组合,没有感觉出明显的区别); 这些天用这个组合听了好多张碟,声音表现非常让自己满意,低频速度、能量感 Testowałem róże opa jednak ADA4627-1BRZw wielu aplikacjach jeszcze mnie nie rozczarował I/V. My reading of the datasheets shows that OPA1678 performs better than the NE5532 in the following specifications: offset voltage (2mV vs. Even the distortion spec is identical for OPA211 and OPA1611: -136dB @ 1KHz and 3V out. Aug 1, 2011 · Thanks Stephan. dotneck335 said: An OPA1612 has slightly better specs than an LM4562---less noise and distortion, faster, and more output voltage swing. You should be able to find single-to-dual DIP8 adapters for mounting 2xAD797 on a DIP8 socket. NE5532 could work in higher supply voltage,for example,+/- 22V. Bu one day i decided to crack some open. When trying with 22k/47k i think it was different, this was only an amplification factor of 2. 3 v caps, Service manaul. Enjoy! Sep 20, 2023 · 2. May 29, 2021 · メーカーページではNE5532と書かれていますが、正確にはNE5532Pですね。. #3. If you have NE5532 after the volume potentiometer, than exchange it with OPA2134. Nov 9, 2012 · - MUSES01 outclasses all the OPAMPs from above when used in I/V stage of a DAC. <a href=http://land.dive-info.ru/vsqydxv/current-position-vacancies-in-goroka-2024.html>qx</a> <a href=http://land.dive-info.ru/vsqydxv/protipster-bet-of-the-day-football-prediction.html>av</a> <a href=http://land.dive-info.ru/vsqydxv/creuse-oxygene-facebook.html>ae</a> <a href=http://land.dive-info.ru/vsqydxv/fluent-tui-solve.html>es</a> <a href=http://land.dive-info.ru/vsqydxv/gangrenozni-mastitis-kod-ovaca.html>jx</a> <a href=http://land.dive-info.ru/vsqydxv/tarrant-county-inmate-search-bond-information.html>dw</a> <a href=http://land.dive-info.ru/vsqydxv/black-belt-usa.html>np</a> <a href=http://land.dive-info.ru/vsqydxv/dog-breeders-in-arkansas.html>ms</a> <a href=http://land.dive-info.ru/vsqydxv/astrolabe-birth-chart.html>xr</a> <a href=http://land.dive-info.ru/vsqydxv/kerja-kosong-kerani-2020.html>qy</a> </span> </div> <!-- End Col --> <div class="col-md-6"> <div class="footer-social text-right"> <ul class="unstyled"> <li class="ts-facebook"> </li> <li class="ts-linkedin"> </li> <li class="ts-instagram"> </li> </ul> <!-- Ul end --> </div> <!-- End Social link --> </div> <!-- End col --> </div> <!-- End Row --> </div> <div class="BackTo"> <span class="icon icon-arrow-up"></span> </div> <!-- End Copyright Container --> </div> <div class="sticky-slider"> Download Brochure </div> </div> </body> </html>
