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. Combined with state-of-the-art circuit design and advanced cutting-edge process technology, the LME49871 current feedback op amp provides superior signal amplification. Operating over a wide supply voltage range of ± 5V and ± 22V, the LME49871 combines extremely low voltage noise density (1.9nV / √ ^Hz) very low THD+N (0.00012%), easily meets the most demanding applications. To ensure that the most challenging loads are driven without compromise, the LME49871 boasts a slew rate of ± 1900V/μs and a high output current capability of ± 100 milliamps. In addition, dynamic range is maximized to drive either supply-voltage 2.9V output stage within the 150Ω load range.
The LME49871 has excellent CMRR (88 dB), PSRR (102 dB), and VOS（0.05mV）Gives excellent amps op amp DC performance.
The LME49871 is an 8-pin narrow SOIC. Demo board.
