LME49871 Datasheet | National Semiconductor

Description The LME49871 is an ultra-low distortion, low noise, ultra high slew rate current feedback operational amplifier optimized and fully specified for high performance, high fidelity applications. bining advanced leading-edge process technology with state-of-the-art circuit design, the LME49871 current feedback operational amplifier delivers superior signal amplification for outstanding performance. Operating on a wide supply range of ±5V to ±22V, the LME49871 bines extremely low voltage noise density (1.9n V/√Hz) with very low THD+N (0.00012%) to easily satisfy the most demanding applications. To ensure that the most challenging loads are driven without promise, the LME49871 has a high slew rate of ±1900V/μs and an output current capability of ±100m A. Further, dynamic range is maximized by an output stage that drives 150Ω loads to within 2.9V of either power supply voltage. The LME49871 's outstanding CMRR (88d B), PSRR (102d B), and VOS (0.05m V) give the amplifier excellent operational amplifier DC performance. The LME49871 is available in an 8- lead narrow body SOIC. Demonstration boards are available.
