It's almost as good as OPA627BM. This Audio Operational Amplifier achieves out-standing AC performance while driving complex Fig. I know that they are high speed Video OpAms that I tried in the setup just for comparative with others and that they have HUGE distortion. My own conclusions with MUSES: In I/V stage: - MUSES8920 is What was omitted from the LM4562/LME49720 history is that the part was cancelled, because the 6" wafer line it was sourced from went way, and then resurrected on a new 8" wafer line. MUSES8820 is the best, IMHO. Either they did this for marketing reasons or the are different chips. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate of ±20V/µs and an output current capability of ±26mA.
