The LME49723 is part of a family of ultra-low distortion, low noise, high slew rate operational amplifiers that are fully optimized and specified for high performance, high fidelity applications. Combined with state-of-the-art circuit design and cutting-edge process technology, the LME49723 audio operational amplifier provides superior audio signal amplification with excellent audio performance. The LME49723 combines a very low voltage noise density (3.6nV / √ ^Hz) with a negligible THD + N (0.0002%), easily suitable for the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49723 ± 20V/μs slew rate and output current ± 26 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.
LME49723 has excellent CMRR (100 dB), (PSRR 100 dB) and VOS（0.3mV），Get excellent amplifier op amp DC performance.
The LME49723 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LME49723 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as its low input bias current. The LME49723 is unity-gain stable.
The LME49723 is an 8-pin narrow body SOIC. Demo boards are provided for each package.
