19 maj 2017 · I have made headphone amps with good 'audio' FET input op amps wrapping 100 MHz DSL driver cfa op amps. the composite multiloop feedback linear stability is much easier to design with the output much faster than the input op amp.
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 · 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. We get lower current noise and better EMI resistence.
The LM4562 is designed for high slew rate, low noise and high output for systems needing +/-2.5 to +/-17V functionality. The pin out is the TI standard to quickly upgrade existing boards. This series is for applications such as high quality audio amplification, multi-media, imaging, line drivers/receivers and active filters.
TI’s LM4562 is a 2-channel, 55-MHz, high-fidelity, high performance audio op amp. Find parameters, ordering and quality information.
29 cze 2004 · high-end opamps would work great for filters and such, but not for audio purposes. the LM4562 and OPA and AD8066 and AD8620 are considered good opamps but they sound extremely muddy and smeared and undynamic.
30 sty 2004 · Looking to buy some opamps for rolling then stumbled on a thread with people saying that the three are the same thing. Some vendors market the same as well. LM4562 and LME49720 are the exact same part... just different model stamped (stated by an ex-employee)
