National Semiconductor Introduces High Current Audio Buffer

National Semiconductor LME49600

The LME49600 is a high performance, low distortion high fidelity 250 mA 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, 110 MHz bandwidth mode that consumes 7.3 mA and a wide 180 MHz bandwidth mode that consumes 13.2 mA. In both modes the LME49600 has a nominal 2000 V/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.
