On listing is two pieces of LME49600 high speed low distortion headphone buffer. 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/?s 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. The listing is for two pieces. We do air shipping worldwide at US$7.00. We welcome combine shipping.
