illustrate
The LME49713 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 cutting-edge process technology, the LME49713 current feedback op amp provides superior signal amplification. Operating over a wide supply voltage range of ± 5V over a ± 18V, the LME49713 combines extremely low voltage noise density (1.9nV/1.9nV/ √ ^Hz) very low THD+N (0.00036%), easily suitable for the most demanding applications. To ensure that the most challenging loads are driven without compromise, the LME49713 has a slew rate of ± 1900V/μs and a high output current capability of ± 100 mA. In addition, dynamic range is maximized to drive either supply-voltage 2.9V output stage within the 150Ω load range.
The LME49713 has excellent CMRR (88 dB), PSRR (100 dB), and VOS（0.05mV）Gives excellent amps op amp DC performance.
The LME49713 is available in an 8-pin narrow-body SOIC and 8-lead metal (TO-99). Demo board.
