The LM4562 is the designated part of an ultra-low distortion, low noise, high slew rate operational amplifier family optimized and comprehensive for high performance, high fidelity applications. Combined with state-of-the-art circuit design and advanced cutting-edge process technology, the LM4562 op amp provides outstanding audio performance and superior audio signal amplification. The LM4562 combines a very low voltage noise density (2.7nV//) √ ^Hz) with vanishingly low THD+N (0.00003%) easily meets the most demanding audio applications. 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 of ±26 mA capability. In addition, the dynamic range is maximized by the output stage, which drives a 2kΩ load with a 1.4V supply voltage of 1V over the term, and a 600Ω load while driving.
And the LM4562 has excellent CMRR (120 dB), PSRR (120 dB) and VOS（0.1mV）Give excellent amplifier op amp DC performance.
The LM4562 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LM4562 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This audio op amp achieves excellent AC performance while driving high complex loads up to 100pF.
The LM4562 offers 8-pin narrow body SOIC, 8-pin plastic DIP and 8-lead metal can TO-99. The demo board is in each package.
