The LME49740MA is an ultra-low distortion low noise high slew rate Operational Amplifier optimized and fully specified for high-performance, high-fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49740 audio operational amplifier delivers superior audio signal amplification for outstanding audio performance. The LME49740 combines extremely low voltage noise density (2.7nV/√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 LME49740 has a high slew rate of ±20V/µs and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that drives 2kR loads to within 1V of either power supply voltage and to within 1.4V when driving 600R loads.
