10 paź 2020 · For me its clear evidence that LM4562 is a very good op amp. I have also tried opa1642, 1612 and 2134, but they are all slightly inferior to lm4562 soundwise in Aiyima a04.
3 sty 2012 · In your first post you say it all seems OK until one particular opamp is replaced. So we need to be methodical and measure (and scope) the power supply to that opamp and all the others as a first check. Lets see what that shows. The LT1072 is a low power switching PSU chip. It might be going into some form of limiting with the extra loading.
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.
15 mar 2014 · My experience with "upgrading" op amps and capacitors has thus far been to degrade the sound. Might be best to leave these newer models alone. - as to a favourite op amp, mine would be the LM4562.
30 paź 2023 · In the first scenario, with the LDO off, the input would likely be violating the common-mode input voltage range of the device as the resistor would pull the pin to ground. This would put the device in a non-linear state.
