I think OPA827 does deliver that. BUF634 adds some of the Burr-Brown character to the sound, but with 827, the sound is drier than with other Burr-Brown opamps, so I don't think that 827 …

Dec 16, 2008 · The OPA2107 has been added to my options for the dual opamp phono preamp, which is a passive design. I have compared the original design, particularly with passive parts …

Oct 10, 2008 · OPA827 Equivalent Circuit. OPA827 is a non-complementary input stage and vas. Followed by a complementary output buffer The input uses 4 N-JFETs, in differential …

Mar 10, 2008 · Hello! I'm looking for the simulation model of the OPA827 to work with TINA-TI (free version). It's not available on the TI web site and the TINA free version do not permit to …

Jul 22, 2013 · Simple diamond buffer based on a WJ design. Enclosed in the feedback loop of an OPA827. DB open loop distortion is 0.0006xx% THD20 at 2Vrms into a 250 Ohm load. …

Feb 25, 2019 · I see no reason to pay a premium for the opa827. The opa1641 does more than fine for much cheaper and can be used non inverting without performance degradation …

With OPA827 and OPA627, the second harmonic (40kHz) was larger than the fundamental wave of 20kHz, and 40kHz was regarded as the fundamental wave, so THD could not be measured. …

Jun 8, 2023 · However, BB(TI) products since the new OPA827 have improved significantly. I am not familiar with the physical properties and process technology of semiconductors, but it may …

Feb 25, 2019 · I have just knocked up a version of the circuit in post 9 with OPA1641's and 2SC5171's on Veroboard. Each channel runs at 200mA and with 18v supplies you need a …

Oct 14, 2013 · This arrangment solves the "DC servo makes the offset worse" problem on the LME49600 datasheet headphone amp given the much lower input offset voltage and input …
