LME49710 High Performance, High Fidelity Audio Operational Amplifier
General Description
The LME49710 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications.

Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49710 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49710 combines extremely low voltage noise density (2.5nV/Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49710 has a high slew rate of ±20V/s and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that drives 2k loads to within 1V of either power suppl
