LME49725 PowerWise® Dual High Performance, High Fidelity Audio Operational Amplifier
General Description
The LME49725 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 LME49725 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49725 combines extremely low voltage noise density (3.3nV/Hz) with vanishingly low THD+N (0.00004%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49725 has a high slew rate of ±15V/s and an output current capability of ±22mA. Further, dynamic range is maximized by an output stage that drives 2k loads
