LME49600; ack loop of op amps. The LME49600 offers a pin-selectable bandwidth: a low curr ent, 110MHz bandwidth mode that consume s 7.3mA and a wide 180MHz bandwidth mod e that consumes 13.2mA. In both modes t he LME49600 has a nominal 2000V/μs sle w rate. Bandwidth is easily adjusted by either leaving the BW pin unconnected or connecting a resistor between the BW pin and the VEE pi.

LME49600
High Performance, High Fidelity, High Current Audio Buffer
General Description
The LME49600 is a high performance, low distortion high fi-
delity 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 cur-
rent, 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.
