LME49725 PowerWise® Dual High Performance, High Fidelity Audio Operational Amplifier April 3, 2008 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/μs and an output current capability of ±22mA. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω 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. Ove...
