The LME49990MA is an Overture E series ultralow distortion, ultra low noise operational amplifier in 8 pin SOIC package. This device is optimized and fully specified for high performance and high fidelity applications. The LME49990 combines low voltage noise density (0.9nV/√Hz) with vanishing low THD+N (0.00001%). It drives 600 ohm loads to within 2V of either power supply voltage. The LME49990 is unity gain stable.
