The LME49860 chip is part of the ultra-low distortion, low noise, high slew rate operational amplifier family, high performance, high fidelity applications, fully optimized and specified. Combined with state-of-the-art circuit design and advanced cutting-edge process technology, the LME49860 chip's audio operational amplifier provides superior audio signal amplification with superior audio performance. The LME49860 chip combines extremely low voltage noise density (2.7nV// √ ^Hz) with a negligible THD + N (0.00003%), easily suitable for the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49860 chip features 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 LME49860 chip has excellent CMRR (120 dB), (PSRR 120 dB) and VOS（0.1mV）Amplifier: Excellent op amp DC performance.
The LME49860 chip has a wide supply voltage range of ± 2.5V to ± 22V. The LME49860 chip maintains excellent common-mode rejection ratio, power supply rejection, and low input bias current over this supply voltage range. The LME49860 chip is unity gain stable. This audio op amp achieves excellent AC performance with complex loads up to 100pF high values when driving.
The LME49860 chip is available in 8-pin narrow SOIC and 8-pin plastic DIP packages. Demo board for each package.
