LME49710 is part of an ultra-low distortion, low noise, high slew rate op amp family that is 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, the audio op amplifier LME49710 provide excellent audio performance and superior audio signal amplification. LME49710 combines an extremely low voltage noise density (2.5nV/^Hz) with a very low THD+N (0.00003%) to meet the most demanding audio applications with ease. To ensure that the most challenging loads are driven without compromise, LME49710 boasts a high slew rate of ±20V/μs and a ±26mA output current capability. In addition, the dynamic range is maximized, driving the output stage when driving a 600Ω load within 1V and 1.4V of either supply voltage over a 2kΩ load range.
LME49710 excellent CMRR (120 dB), (PSRR120 dB) and V OS (0.05mV) give excellent op amp DC performance for the amplifier.
LME49710 has a wide supply voltage range ± 2.5V to ± 17V. LME49710 input circuitry maintains excellent common-mode and supply rejection over this supply voltage range, as well as maintaining its low input bias current. LME49710 is stable unit gain. The audio op-amp achieves excellent AC performance with high values of up to 100pF for complex loads while driving.
LME49710 are available in an 8-pin narrow-body SOIC package, an 8-pin plastic DIP, and an 8-lead metal can TO-99. Each package presentation board.
