illustrate

The LME49725 is part of a family of ultra-low distortion, low noise, high slew rate operational amplifiers optimized and fully specified for high performance, high fidelity applications. Combined with state-of-the-art circuit design and cutting-edge process technology, the LME49725 audio operational amplifier provides superior audio signal amplification with excellent audio performance. The LME49725 combines a very low voltage noise density (3.3nV/) ^Hz) with a negligible THD+N (0.00004%), easily satisfying the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49725's ±15V/μs slew rate and output current ± 22 mA capability. In addition, dynamic range is maximized to drive 1V of either supply voltage within 1.4V of a 2KΩ load and an output stage within a 600Ω load.

Part of the PowerWise ® family of energy-efficient solutions, the LME49725 consumes only 3.0 mA of supply current per amplifier while delivering superior performance for high-performance, high-fidelity applications.

The LME49725 has excellent CMRR (120 dB), (PSRR 120 dB), andVThe OS (0.5mV) gives excellent amp op amp DC performance.

The LME49725 has a wide supply voltage range of ± 4.5V to ± 18V. The input circuitry of the LME49725 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as maintaining its low input bias current. The LME49725 is unity-gain stable. This audio op amp achieves excellent AC performance with high values of up to 100pF when driving complex loads.

The LME49725 is an 8-pin narrow body SOIC.
