The LME49720MA/NOPB 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 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. It 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 LME49720MA/NOPB 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. Outstanding CMRR (120dB), PSRR (120dB) and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance.
