FEATURES
DESCRIPTION
The LME49600 is a high performance, low distortion
2
Pin-Selectable Bandwidth and Quiescent
high fidelity 250mA audio buffer. The LME49600 is
Current
designed for a wide range of applications. It can be
Pure Fidelity, Pure Performance
used inside the feedback loop of op amps.
Short Circuit Protection
The LME49600 offers a pin-selectable bandwidth: a
Thermal Shutdown
low current, 110MHz bandwidth mode that consumes
7.3mA and a wide 180MHz bandwidth mode that
TO–263 Surface-Mount Package
consumes 13.2mA. In both modes the LME49600 has
a nominal 2000V/
μs slew rate. Bandwidth is easily
APPLICATIONS
adjusted by either leaving the BW pin unconnected or
Headphone Amplifier Output Drive Stage
connecting a resistor between the BW pin and the
Line Drivers
VEE pin.
Low Power Audio Amplifiers
The LME49600 is fully protected through internal
current limit and thermal shutdown.
