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 to within 1V of either power supply voltage and to within 1.4V when driving 600 loads. Part of the PowerWise family of energy efficient solutions, the LME49725 consumes only 3.0mA of supply current per amplifier while providing superior performance to high performance, high fidelity applications. The LME49725's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.5mV) give the amplifier excellent operational amplifier DC performance. The LME49725 has a wide supply range of 4.5V to 18V. Over this supply range the LME49725's input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LME49725 is unity gain stable. This audio operational amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF.
