The LME49740 is part of the ultra-low distortion, low noise, high slew rate operational amplifier family, high performance, high fidelity application optimization and full specification. Combined with state-of-the-art circuit design with advanced cutting-edge process technology, the LME49740 audio operational amplifier provides superior audio signal amplification with superior audio performance. The LME49740 combines extremely low voltage noise density (2.7nV/) √ ^ HZ) with a negligible THD + N (0.00003%) for the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49740 boasts a high slew rate of ± 20V/μs and an output current capability of ±26 mA. In addition, dynamic range is maximized when driving an output stage within 1V and 1.4V of either supply voltage within a 2kΩ load range.

The LME49740 has excellent CMRR (120 dB), (PSRR 120 dB) and V_{OS（0.1mV）}Amplifier: Excellent op amp DC performance.

The LME49740 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LME49740 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as its low input bias current. The LME49740 is unity-gain stable. Audio op amps achieve excellent AC performance with complex loads up to 100pF high values when driving.

The LME49740 is available in a 14-pin narrow body SOIC and a 14-pin plastic DIP. Demo board for each package.
