The LME49743 is a low distortion, low noise, high slew rate operational amplifier optimized and fully specified for high performance, high fidelity applications. The LME49743 audio operational amplifier delivers superior audio signal amplification for outstanding audio performance. The LME49743 combines low voltage noise density (3.5nV/Hz) and THD+N (0.0001%) to easily satisfy demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49743 has a slew rate of 12V/s and an output current capability of 21mA. The LME49743's outstanding CMRR(106dB), PSRR(98dB), and VOS (0.15mV) give the amplifier excellent operational amplifier DC performance.
