The LM4562 is a specified part of the ultra-low distortion, low noise, high conversion rate op amp series optimized and comprehensive high-performance, high-fidelity applications. Combining the state-of-the-art circuit design with advanced and cutting-edge process technology, the LM4562 op amplifier delivers 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%) to easily meet 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 ±26mA. In addition, the dynamic range is maximized by the output stage, which drives a 2kΩ load, a 1.4V supply voltage of 1V, and a 600Ω load while driving.

The LM4562's excellent CMRR (120 dB), PSRR (120 dB) and V OS (0.1mV) give the amplifier excellent op-amp DC performance.

The LM4562 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LM4562 over this supply voltage range maintains excellent common-mode and supply rejection, as well as maintains its low input bias current. The LM4562 is unit gain stable. This op-amp achieves excellent AC performance while driving high complex loads with values up to 100pF.

The LM4562 is available with an 8-pin narrow-body SOIC, an 8-pin plastic DIP, and an 8-lead metal can TO-99. Demo boards are per package.
