In comparing the spec sheets of OPA627B and ADA4627B-1, the current noise specs are identical (1. 2010-06-10 8:32 am. 1nv). when we use opa1612 to translate difference input to single-ended output, the output is distorted, pls. in some line level circuitry. This will kind of be a comparison of the OPA1612 to the Burson V5i. Unfortunatly with the new OPA1612 I have obtained a lot of noise on the output channel. These would toast. Discrete circuits where you can implement them using jfets , are perhaps the best for audio. Over this supply range the LME49860 maintains excellent common-mode rejection, power supply rejection, and low input bias current. There are several motherboard designs that are emphasizing high impedance headphones (they …. It seems like LM4562 in SOIC-8 package is rather unobtainable at the moment so I'm thinking about suitable alternatives. If your opamp it is not in that place, after a potentiometer, then you leave it , dont change it. over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Voltage Supply voltage, V Of the op amps in my collection the massive misbehavers are the OPA1656, the LME49990 and the OPA1612. I've used both LM4562 and OPA2604 from the suggestions. ®. まだ細かいところを調整していますが、オペアンプをLTC6227に交換してみます。. THD+N (AV = 1, VOUT = 3VRMS, fIN = 1kHz) RL = 2kΩ.

The picture shows my op-amp rolling, I have tried the ne5532, opa1612, lm4562 and I found that OPA1612 was in the ultimate soundplus collection that's why i have change for it. THD+Noise vs Frequency Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages in standard configurations. Figure 43 illustrates a second order low pass filter commonly encountered in signal processing applications. so with a -12. 4mm pentaconn the good thing about D30 display + Bluetooth If you have questions about quality, packaging or ordering TI products, see TI support. #13. J. These op amps supply low offset voltage, low drift over temperature, low bias current, and low noise with only 60-nV RMS 0. Previously I am using BB OPA1642. Joined 2009. The sparkos opamps are very good as well but are IMO sonically warmer than the Sonic Imagery. It is louder at the same setting compared to any of the IC designs. If you are not aware of the type and function of the opamp, do nothing or replace it with OPA1611. The OPA627 and OPA637 are ideally suited to construct high speed, high precision active filters. The opa2132/4 are great and not that expensive while maintaining excellent specs. I couldn't tell the difference between the The SS3601 / SS3602 discrete op amps will outperform virtually all audio grade monolithic IC op amps in open loop gain, noise performance, output current, and magnitude of class A bias current. TL072 was VERY good !! Equal or better than 4562 in some respects. Even the coveted … The OPA1612 opamp has similar specs to the AD797 and it is considerably cheaper, plus it has 2 opamps in a single package VS the AD797 which has a single opamp.

(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. I prefer a bipolar opamp but a low noise FET will do, the LME49740 would've been perfect but it is now discontinued. If you have questions about quality, packaging or ordering TI products, see TI support. 4dBu EIN. Joined 2011. There's no premium grade components. The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low. The good thing about the tone 2 pro Balanced, output RCA or 4. You won't find things like OPA1612. Which is fine. try modding with better FET input opamp, like OPA2107 or OPA2111. The OPA1612 does not seem to have the process contamination of the LM497X0 that produces rocky-sounding noise. This takes a slight … So considering NE5532, LM4562 and OPA2134, OPA2134 gives best measured results in AIYIMA A07. Hello together, i want to put one of the mentioned OP Amps in my amp. I still want to try (in the DAC I mentioned) the THS4051 and the OPA1611. The new … So for a low cost the LM4562 or OPA2134. The LM4562 is superior in just about every parameter, but it has much higher current noise. I have fitted 78L12/79L12 regulators close to the AD8066, and replaced the manufacturer recommended 100nF ceramic bypass capacitors with normal 100nF 63V types. SMSL DAC M300MarkII 改造7 オペアンプ交換 LM4562→OPA1612. I've never used one but it has excellent specs. It doesn't say or show in the datasheets. The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600 mV with a 2-kΩ load, which increases headroom and maximizes dynamic range. Prodigy 230 points. NE5532 it is a very good opamp. at +/-20Vdc, drawing about 8mA. Review of LM4562 IC. The LM4562 combines extremely low voltage noise … Sep 20, 2023.

The lm4562 is technically proven better than ne5532 in this amplifier. An OPA1612 has slightly better specs than an LM4562---less noise and distortion, faster, and more output voltage swing. That input stage it is not properly for a volume potentiometer. (€20 DAC) vs a Topping E30 II (150€) vs the internal DAC on a Marantz CD-Player. Other op amps you can try are AD823's but they can be a bit noisy when used at the inputs of a phono stage so I prefer them in the output stages. The OPA1641 would be slightly better. If it is noticeable, that is subjective. I don't like the ratchet encoder in Topping, it feels like a very cheap device. I primarily use iems and headphones and Anyone know whether the LM4562-LME49710-LME49860 series are PNP input or NPN . OPA2210: Audio applications. 5V to ±18V. At present it also has a much higher price, but hopefully that will change. All are specified for –40°C to 85°C operation. UAN said: This means that a better quality encoder is installed in the A30. Opa1612 and LM4562/LME49720 are both good. rcs16 said: If the replacement is a Signetics NE5532A part then they will sound the same. You can also try OPA1612 as buffer with OPA2822 for the headphone driver. I have tried ne5532, opa2604, lm4562 and opa1612 and I prefered LM 4562 in both Aiyima a07 and the tpa3251-based Aiyima a04. The LME49860 has a wide supply range of ±2. Canada. The OPA1662 (dual) and OPA1664 (quad) series of bipolar-input operational amplifiers achieve a low 3. Many people have already replaced 5534 with 627 and it is supposed to work fine. T. #1 Choose the LM4562 (LM4562 vs NE5532): High-End Audio Quality: If your application demands the highest audio quality, low distortion, and minimal noise interference, the LM4562 is a better choice. Device Information(1) The Aiyima a04 with lm4562 is dead quiet - no hiss at all.
