Opa1611 vs ne5534. Hi there, i'm designing the PCB for a DAC using a PCM179x (either 1798 or 1794a), and have a few questions regarding the layout of components I hope you may be able to help me with. My statements were verified: - OPA1611/1612 are optimized for better distortion than the OPA211 (already pretty good). I’m going to solder the IC to a soic to dip adapter then plug it into the the amp. I'll be comparing the OPA1641 with the ADA4610 in a Walt Jung shunt regulator soon so I'm interested in the result as well. OPA827's applications include transimpedance amp, Also LME49710/720 is a very good sounding opamp as I/V, just a bit less musical than OPA827. Compared to other operational amplifiers, such as TL083, they show better noise performance, improved output drive capability, and considerably higher Using a suitable Op-Amp (e.
