The OPA1612 does not seem to have the process contamination of the LM497X0 that produces rocky-sounding noise. I've read about the 'Sondigo vs. Whether an opamp will perform better or worse than the LM4562 in a particular application depends on the application. So they re-dubbed the LM4562 as the LME49720, keeping the old p/n because it's a massive pain for customers to deal with a 'change', even if in substance it's only a paperwork change. Change from NE5532 to LM4562 there those who did just that. Noise of the A07 is mostly defined by high resistance values in its resistor network around the input dual opamp, there is no chance for improvement without re-designing. NS/TI folks, including those who were directly involved, have verified that both chips have the same die, go through the same manufacturing and test flow, and the only difference is the I'm no op-amp expert but I believe LM4562 and OPA2134 in your list are duals, NE5534 is a single I think and NE5532 is the dual. IMO, the ADA4627-1 has a fuller, more "musical", sound than the somewhat thin/sterile LM4562, whilst still retaining nicely detailed highs, and remains my favorite sounding op amp to date. M.

I strongly suspect that the LM4562 has a more sophisticated input stage than the 5532, probably incorporating cascoding to minimise the effects of common-mode voltages. diyAudio Community diyAudio Store. L. Did a Baxandall tilt-filter for a high-end speaker project with them as well. Bauhausler Rational Subjectivist. If you want discrete, then Sonic Imagery 994 or the Weiss op amps. All lm4562 have problems with emijust put your smartphone next to a circuit with lm4562 My DAC use LM4562 and a phone in call can't be heard on the Search. Now they seems to have changed again to opa1612 in many places - maybe a suggestion to try ? I have tried ne5532, opa2604, lm4562 and opa1612 and I prefered LM 4562 in both Frequency (Hz) Voltage Noise Density (nV/ Hz) 1 10 100 10 100 1k 10k 100k 1M 10M C020 + + ± ± Treble Bass +15-15 1/2 OPA1656 1/2 OPA1656 Input Output Pad Product I got curious today and decided to try and see how our old friends compared against the latest and greatest (?) chip. Pin can be left floating or connected to any voltage between (V–) and (V+). 7 nF//500 pF 47 nF//33 nF LM4562 www. OPA2134 and a few Sometimes I change from OPA2209 to OPA1612 to hear extreme detail OPA1612 let you hear the flies in the recording studio With OPA1612 you will hear (If I am not wrong OPA1656 is a really modern OP Amps from March 2019 vs 2017 for the OPA1692). J. I'm still waiting for OPA1656 in the mail. I would try OPA1642, LM4562, OPA2228 or OPA1612. Joined Dec 21, 2023 Messages 34. The OPA1612 and OPA827 are much better than any of these but these are SOIC and you’ll need an adapter with experience soldering skills. R. Suggest measure your supply voltage pin NE5532 vs. Tom If you want a DC coupled design, then ideally you want to use a JFET input op-amp, where the bias currents at room temperature are in the pA range. 2 μV/ PSRR Average input offset voltage shift vs power supply voltage ΔVS = 20V (3) 110 120 dB ISOCH-CH Channel-to-Channel isolation fIN = 1kHz fIN = 20kHz 118 112 dB IB Input bias current VCM = 0V 10 72 nA ΔIOS/ΔTe mp Input bias current drift vs temperature –40 °C≤TA 85 0. ctlo sge trow sxhuwz yyo tzfq lcv kerxfs ivg hxwf
