LME49722 is part of a series of ultra-low distortion, low noise, high slew rate operational amplifiers, high performance, high fidelity applications, fully optimized and specified. Combined with the state-of-the-art circuit design and advanced cutting-edge process technology, LME49722 audio op-amplifier can provide excellent audio performance and superior audio signal amplification. LME49722 combined with very low voltage-noise density (1.9nV/) √ Hz) with a very low THD+N (0.00002%), easily meeting the most demanding audio applications. To ensure that the most challenging loads are uncompromising drives, LME49722 boasts a high slew rate of ±22V/μs and an output current capability of ±28 mA. In addition, the dynamic range maximizes the drive of a 1V output stage of any supply voltage over a load range of 2kΩ.

LME49722 has a wide supply voltage range ± 2.5V to ± 18V. LME49722 maintains excellent common-mode and supply rejection over this supply voltage range with low input bias current. The op-amp achieves excellent AC performance with a gain value greater than 2 high with complex loads up to 100pF while driving. Directly similar to the LME49720, the LM4562 and LME49860 chips are interchangeable.
