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. Combining
advanced leading-edge process technology with state-of-the-art circuit design, the LME49721
Rail-to-Rail Input/Output operational amplifier delivers superior signal amplification for
outstanding performance. The LME49721 combines a very high slew rate with low THD+N to easily
satisfy demanding applications. To ensure that the most challenging loads are driven without
compromise, the LME49721 has a high slew rate of ±8.5V/μs and an output current capability of
±9.7mA. Further, dynamic range is maximized by an output stage that drives 10kΩ loads to within
10mV 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 common-mode and power supply rejection, as well as
maintaining its low input bias current. The LME49721 is unity gain stable.
