19 maj 2017 · By most standards the LM4562 is a superior op-amp to the NE5532. I'm still (perhaps irrationally) fond of the OPA604, maybe because some equipment I really like used it. That's a FET input op-amp though.
23 lut 2019 · #1. AIYIMA A07 TPA3255 Amplifier Measurements LM4562 option. I received my A07 yesterday, on January 6, 2021, shipped from Italy. Purchased at Amazon.de and as stated on their website, it arrived without a power supply. I am testing the A07 with 2 different power supplies.
25 lis 2015 · For DIY amps, there are forums for electrical engineering hobbyists that can help suggest an op amp that will fit for your particular circuit design. Sure, a DIY amp is going to require some op amp rolling for testing, after all you are the one engineering it.
7 sty 2021 · We have now SINAD = 88dB at 5W/4ohm/1kHz and @24kHz BW. So considering NE5532, LM4562 and OPA2134, OPA2134 gives best measured results in AIYIMA A07. And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here.
3 sty 2023 · Ordered some LM4562 op-amps today from Mouser just for the heck of it. I may try those in the A04 first and see how they do. I've pulled the AO100 to do some testing of it with a subwoofer in another room.
This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in an 8-lead narrow body SOIC, an 8-lead PDIP, and an 8-lead TO-99.
17 paź 2014 · You can try the LME47920HA's or the LME49990 (single opamp so you need 2 SOIC8's to a single dual DIP8 conversion) if you like the LM4562's sound signature. Edited October 17, 2014 by DefQon Link to comment
