The LME49720 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fullyspecified for high performance, high fidelity applications. Combiningadvanced leading-edge process technology with state-of-the-artcircuit design, the LME49720 audio operational amplifiers deliver superior audio signal amplification for outstanding audioperformance. The LME49720 combines extremely low voltage noise density (2.7nV/√^Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challengingloads are driven without compromise, the LME49720 has a high slew rate of ±20V/μs and an output current capability of ±26mA.Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage andto within 1.4V when driving 600Ω loads.
The LME49720's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance.
The LME49720 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49720’s input circuitry maintains excellentcommon-mode and power supply rejection, as well as maintaining its low input bias current. The LME49720 is unity gain stable.This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF.
