Operational Amplifiers - Op Amps HI-PERF, HI-FI, HIGH CURRENT AUDIO BUFFER
The LME49740 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49740 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49740 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 challenging loads are driven without compromise, the LME49740 has a high slew rate of ±20V/s and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that drives 2k loads to within 1V of either power supply voltage and to within 1.4V when driving 600 loads.
The LME49740's outstanding CMRR(120dB), PSRR(120dB), and VOS(0.1mV) give the amplifier excellent operational amplifier DC performance.
The LME49740 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49740's input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LME49740 is unity gain stable. The Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF.
The LME49740 is available in 14lead narrow body SOIC and 14lead plastic DIP. Demonstration boards are available for each package.
