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 the country's most advanced circuit design and advanced cutting-edge process technology, the excellent performance of LME49713 current feedback operational amplifier provides superior signal amplification. Operating at ± 5V, the wide supply voltage range is ± 18V, LME49713 combined with very low voltage-noise density (1.9nV/) √ ^Hz) very low THD + N (0.00036%), easily meeting the most demanding applications. To ensure that the most challenging loads are uncompromising drives, LME49713 boasts a slew rate of ±1900V/μs and a high output current capability of ± hundredmA. In addition, the dynamic range maximizes driving any supply voltage 2.9V output stage over the 150Ω load range.
LME49713 excellent CMRR (88 dB), PSRR (100 dB), and V OS (0.05mV) give excellent op amp DC performance for amplifiers.
LME49713 is in an 8-pin narrow-body SOIC and 8-lead metal (TO-99). Demo board.
