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.
30 sty 2004 · The LME49720 output stage is optimized for supply voltages under +-17 volts. The LME49860 is optimized for +-14.5 to 22 volts. The LM4562 is similar to the LME49720 except it's in a metal case and has better heat dissipation and drives 600 ohms effortlessly.
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.
19 sty 2023 · Be sure to include the AD746, the OPA2209, and the ADA4898-2 (mounted on SOIC-to-DIP adapters) in your rotation. And of course the OPA1612. I ran a double blind listening test of dual opamps a couple years ago and the grandfatherly old LF412 was shockingly highly rated.
30 maj 2023 · The LM4562 has undeniably set the cat among the pigeons, pushing the envelope and setting a new benchmark for op-amps in the audio realm. It's akin to a high jumper effortlessly clearing the bar, raising it for others to aspire to.
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.
24 sie 2018 · For the dual op-amps you can see one of the op-amps is configured for inverting 6dB gain with 10k and 4.99k resistors. The second op-amp is unity gain buffer. Both op-maps have the option to add either a 1k, 2k, or 10k load via the 2-pin jumper headers J1, J2, J3, J4, J5 and J6.
