DESCRIPTION
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.
