The best solution is actuallly to bypass +V to ground, and -V to ground. It provides a wider bandwidth, lower noise, and higher slew rate compared to the NE5532. They are the three that are the consistently best performers. A little better than the stock opamps. In audio, you may get by with a V+ to V- bypass, but if the goal is to stablize the supply while its output delivers current to ground, then the bypasses really should be to ground. I strongly suspect that the LM4562 has a more sophisticated input stage than the 5532, probably incorporating cascoding to minimise the effects of common-mode voltages. Jun 10, 2010 · The LM4562 is a great substitution for the 5532. For FET input the OPA2604 and OPA2134 types are recommended. Tucson Blvd. This has been dispelled by people employed by NS and TI -- back then and currently. The fastest slew rate a needle in a vinyl LP track can provide is in the region of 2-3 V/us, I seem to remember an old IEEE recommendation of 6 V/us as plenty for vinyl audio hi-fi use. com SNAS326K –AUGUST 2006–REVISED DECEMBER 2013 LM4562 Dual High-Performance, High-Fidelity Audio Operational Amplifier Check for Samples: LM4562 1FEATURES DESCRIPTION The LM4562 is part of the ultra Jul 5, 2006 · Hi All, Can OPA2604 be directly swap with LM4562/LME49720HA/LME49860 in a DA output? thANKS. 5A.
