LME49610 Datasheet | National Semiconductor

Description The LME49610 is a high performance, low distortion high fidelity 250m A audio buffer. The LME49610 is designed for a wide range of applications. When used inside the feedback loop of an op amp, it increases output current, improves capacitive load drive, and eliminates thermal feedback. The LME49610 offers a pin-selectable bandwidth: a low current, 120MHz bandwidth mode that consumes 13m A and a wide 200MHz bandwidth mode that consumes 19m A. In both modes the LME49610 has a nominal 2000V/μs slew rate. Bandwidth is easily adjusted by either leaving the BW pin unconnected, connecting it to the VEE pin or connecting a resistor between the BW pin and the VEE pin. The LME49610 is fully protected through internal current limit and thermal shutdown.
