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.
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.
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 · It seems paying a few more dollars for LM4562 op amp instead of NE5532 doesn't really make much sense. LM4562 may be slightly better, but the difference is not audible. Click to expand...
The LM4562 A07 does work really well if you feed it with a good preamp like the Aiyima T6 Pro which also is flexible when it comes to op amps. I tested a few in both units and the best combination to my ears at least is the opa2604 in the output stage of the T6 Pro and the LM4562 in the A07.
28 sie 2023 · The LM4562 is a high-performance audio operational amplifier (op amp) manufactured by Texas Instruments. The LM4562 is a dual-channel op amp, meaning it contains two separate op amps within a single IC package.
