说明

The LME49600 is a high performance, low distortion high fidelity 250mA audio buffer. The LME49600 is designed for a wide range of applications. It can be used inside the feedback loop of op amps.

The LME49600 offers a pin-selectable bandwidth: a low current, 110MHz bandwidth mode that consumes 7.3mA and a wide 180MHz bandwidth mode that consumes 13.2mA. In both modes the LME49600 has a nominal 2000V/μs slew rate. Bandwidth is easily adjusted by either leaving the BW pin unconnected or connecting a resistor between the BW pin and the VEE pin.

The LME49600 is fully protected through internal current limit and thermal shutdown.
