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.
7 sty 2021 · I use an A07 with a Drok 48v, 10 amp adjustable power supply, and run Dali Spektor 2 speakers with it. I think it performs excellent. I run OPA1656 op amps just for the hell of it and I also have it ventilated by using a simple template I created:
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.
17 paź 2014 · Today I changed one of the op amp chips in one of my remaining DIY ESP P06's from an LM833 to an LM4562 making both op amp chips LM4562's. It really is a very fine sounding dual op amp if not the most 'musical', yet endearing in its own way.
This Audio Operational Amplifier achieves out-standing AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in 8–lead narrow body SOIC, 8–lead Plastic DIP, and 8–lead Metal Can TO-99. Demonstration boards are available for each package.
