3 paź 2024 · Defective LM4562 opamp ICs with "popcorn" noise. I found that some of my stash of LM4562 opamp chips are defective. Lot # of noisy parts: 99AE96G3, 99AHFNG3, JR21AFE3, 1CZDJ7G3 Support this...
13 sty 2024 · The preamplifier uses a high pass and low pass filter at the input to set the bandwidth, then an input buffer stage with parallel LM4562 op-amps. The input impedance is set to 47.1K. The input buffer stage is followed by a Baxandall active volume control circuit.
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.

20 lut 2009 · I now use the LM4562 opamp in circuits where I need low noise, low THD & IMD, while driving low-impedance loads. In many applications the LM4562 fills the gap between two of my favorite op-amps; the AD797 and the NE5532. All three opamps have outstanding noise performance as well as very low IMD.
