Easily Drives 150Ω Loads  
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. Combining  
advanced leading-edge process technology with  
state-of-the-art circuit design, the LME49713 current  
feedback operational amplifier delivers superior signal  
amplification for outstanding performance. Operating  
on a wide supply range of ±5V to ±18V, the  
LME49713 combines extremely low voltage noise  
density (1.9nV/√Hz) with very low THD+N (0.00036%)  
to easily satisfy the most demanding applications. To  
ensure that the most challenging loads are driven  
without compromise, the LME49713 has a high slew  
rate of ±1900V/μs and an output current capability of  
±100mA. Further, dynamic range is maximized by an  
output stage that drives 150Ω loads to within 2.9V of  
either power supply voltage.  
Optimized for Superior Audio Signal Fidelity  
Output Short Circuit Protection  
100dB (Typ) PSRR and 88dB (Typ) CMRR
