产品概述

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.
