LME49860:flat and boring <-----> LT1358: lower resolution, higher distortion Do you agree on my acoustical ...

2019年12月9日 · - 4) Matrix HPA-3B: swapped the default LME49860 opamps from the Voltage-Amplification Stage with the following: Burson SS V6/MUSES01/02/8820/8920 etc. I noticed a decrease of the background noise, even when using LME49720, despite it should be identical with LME49860 (who knows, maybe these LME49860 were fakes).

2012年7月14日 · lme49860 I am trying to design a series of high fidelity portable amps that will use either one of the chips above, but I don't know enough about audiophile resistors, components etc to make a decent system or even electronics 😕 .

2007年8月22日 · Having had a quick look the data sheet of the LM4562 August 2006 and of the LM49860 June 2007, the differences I detected were at the end of the documents : no mention of "banned substance compliance compliance" at the end of the LME49860 datasheet. The datasheet of the LM49720, May 2007, seems identical on all specs.

2019年6月23日 · The LME49860 has better figures for imd and thd+ noise at 5v output level, then it goes off a cliff in either direction and performance is worse that the OPA1612. if you don't sit with the volume at 0db the whole time the OPA1612 …

2017年11月18日 · I thought LM4562 and LME49860 are the same part. OPA627 is a dielectric isolate jfet input, different animal.

2012年11月9日 · My original plan was to replace the 2 input stage OP-275 with LME49860 because Zapco replace the OP-275 in their latest AP model power amplifer to LME 49720 (and LME 49860 is a better 49720). Then I will replace the remaining 5 …

2014年2月4日 · I think this has all been discussed before, but comparing datasheets for LM4562, LME49720, and LME49860, they sure look strikingly similar. Main exception would be LME49860 is specified for higher voltage rails. IME they are very good audio opamps, but a possible weak point may be their sensitivity to radiated RF.

2018年3月5日 · Interesting that solid-state "opamps" (SGA-HVA-1 & SK99 & SK25) are measuring extremely well and the well-known LME49860 (LME49720 and NE4562) is just a tad lower in performance. +20 dBU means lot of gain, so these opamps should perform admirable when used in voltage amplification gain.
