The LM4562 has a wide supply range of 2. If it is noticeable, that is subjective. If the impedance seen by the input is greater than about 2k925, the LM4562 will be more noisy, than the NE5532. The LM4562 is a National Semiconductor op-amp very popular with builders and upgraders. At only 29mm (1. Tested a lot of OP, including LME49720, OPA1612, OPA1642, MUSES8920 and MUSES8820. The LM4562 is electrically identical to the LME49720 but cheaper ($3) and comes in a DIY friendly DIP8 package. 00002%) to easily satisfy the most demanding audio applications. 03% (please take into account that the equivalent gain is 86dB), one of the lowest noise from all parts under test and no unexpected spectral interference lines. A low impedance cartridge (like, say a Grado) will run quieter with the LM4562. • Input Noise Density: 2. Figure 30. The output is capable of driving 600 loads to 10 V rms while maintaining low distortion. The LM4562 has a wide supply range of ±2. Transients were still good but the HF levels seemed to be a bit rounded off. I have a pre-amplifier built using NE5532 with excellent performance outweighing most high end pre-amplifiers. od if tf gp qy nu ef hl mw ga
