illustrate
The LME49710 is part of a family of ultra-low distortion, low noise, high slew rate operational amplifiers, high performance, high fidelity optimized and fully specified applications. Combined with state-of-the-art circuit design and cutting-edge process technology, the LME49710 audio op amp provides superior audio performance with superior audio signal amplification. The LME49710 combines a minimally low THD+N (0.00003%) extremely low voltage noise density (2.5nV/^Hz) to easily meet the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49710 has 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 LME49710 has excellent CMRR (120 dB), (PSRR 120 dB) and VOS（0.05mV）Gives excellent amps op amp DC performance.
The LME49710 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LME49710 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as maintains its low input bias current. The LME49710 is unity gain stable. Audio op amps achieve excellent AC performance with complex loads up to 100pF high values when driving.
The LME49710 is available in an 8-pin narrow body SOIC package, an 8-pin plastic DIP and an 8-lead metal can TO-99. Demo board for each package.
