LME49721
LME49721 is High Fidelity Rail-to-Rail Input/Output Audio Operational Amplifier manufactured by National Semiconductor.
Description
The LME49721 is a low distortion, low noise Rail-to-Rail Input/ Output operational amplifier optimized and fully specified for high performance, high fidelity applications. bining advanced leading-edge process technology with state-of-the-art circuit design, the LME49721 Rail-to-Rail Input/Output oper.. ational amplifier delivers superior signal amplification for outstanding performance. The LME49721 bines a very high slew rate with low THD+N to easily satisfy demanding applications. To ensure that the most challenging loads are driven without promise, the LME49721 has a high slew rate of ±8.5V/μs and an output current capability of ±9.7m A. Further, dynamic range is maximized by an output stage that drives 10kΩ loads to within 10m V of either power supply voltage. The LME49721 has a wide supply range of 2.2V to 5.5V. Over this supply range the LME49721’s input circuitry maintains excellent mon-mode and power supply rejection, as well as maintaining its low input bias current. The LME49721 is unity gain stable.
