The LME49720 is optimized for ultra-low distortion, low noise, high slew rate operational amplifier series optimization, high performance, high fidelity applications. Combined with the country's most advanced circuit design and advanced cutting-edge process technology, the audio op amplifier LME49720 provide outstanding audio performance and excellent audio signal amplification. LME49720 combined with very low voltage noise density (2.7nV/ √ ^Hz) with vanishingly low THD+N (0.00003%) to easily meet the most demanding audio applications. To ensure that the most challenging loads are driven by no compromise, LME49720 has a high slew rate of ±20V/μs and an output current of ±26mA capability. In addition, the dynamic range is maximized by the output stage, which drives a 2kΩ load, a 1.4V supply voltage of 1V, and a 600Ω load while driving.
LME49720 excellent CMRR (120 dB), PSRR (120 dB) and V OS (0.1mV) give excellent op amp and amplifier DC performance.
The LME49720 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry LME49720 this supply voltage range maintains excellent common-mode and supply rejection, as well as maintaining its low input bias current. The LME49720 is stable unit gain. This op-amp achieves excellent AC performance while driving high complex loads with values up to 100pF.
LME49720 offers 8-pin narrow-body SOICs, 8-pin plastic DIPs, and 8-lead metal cans TO-99. Demo boards are per package.
