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.
Noise comparison test of operational amplifier ICs. I wanted to test the background noise of these ICs. To make it more audible for the video, I recorded eac...
23 lut 2019 · 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.
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.
7 sty 2021 · One can almost not find two more different sounding IC:s. The first one is sounding warm and innofensive, and the LM 4562 is cleaner and leaner. Both are musically better than ne5532, in my subjective opinion. The opa2604 is a fet opamp and 4562 is a bipolar based IC.
