illustrate

LME49725 is part of a family of ultra-low distortion, low noise, high slew rate operational amps that are optimized and fully specified for high-performance, high-fidelity applications. Combined with the country's most advanced circuit design and advanced cutting-edge process technology, LME49725 audio op amplifier provides excellent audio performance and superior audio signal amplification. LME49725 combined with very low voltage-noise density (3.3nV/) √ ^Hz) with a very low THD + N (0.00004%), easily meeting the most demanding audio applications. To ensure that the most challenging loads are uncompromising drives, LME49725 ± 15V/μs slew rate and output current ± 22 mA capability. In addition, the dynamic range is maximized, driving a 2KΩ load of 1V for any supply voltage in the range of 1.4V and an output stage when driving a 600Ω load internally.

Some PowerWise ® energy-efficient solutions in the home consume only 3.0 milliamps of power supply current LME49725 each amplifier while providing superior performance for high-performance, high-fidelity applications.

LME49725 excellent CMRR (120 dB), (PSRR120 dB), and V OS (0.5mV) give the amplifier excellent op-amp DC performance.

LME49725 has a wide supply voltage range ± 4.5V to ± 18V. LME49725 input circuitry maintains excellent common-mode and supply rejection over this supply voltage range, as well as maintaining its low input bias current. LME49725 is stable unit gain. The audio op-amp achieves excellent AC performance with high values of up to 100pF for complex loads while driving.

LME49725 is an 8-pin narrow-body SOIC.
