Features Pin-selectable bandwidth and quiescent current Pure fidelity. Pure performance Short circuit protection Thermal shutdown TO–263 surface-mount package Description The LME49610 is a high performance, low distortion high fidelity 250mA audio buffer. The LME49610 is designed for a wide range of applications. When used inside the feedback loop of an op amp, it increases output current, improves capacitive load drive, and eliminates thermal feedback. The LME49610 offers a pin-selectable bandwidth: a low current, 120MHz bandwidth mode that consumes 13mA and a wide 200MHz bandwidth mode that consumes 19mA. In both modes the LME49610 has a nominal 2000V/μs slew rate. Bandwidth is easily adjusted by either leaving the BW pin unconnected, connecting it to the VEE pin or connecting a resistor between the BW pin and the VEE pin. The LME49610 is fully protected through internal current limit and thermal shutdown.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
