LME49870 is part of an ultra-low distortion, low noise, high slew rate op amp family, high performance, high fidelity application optimization and full specification. Combined with the state's most advanced circuit design and advanced cutting-edge process technology, LME49870 audio op amplifier can provide excellent audio performance and superior audio signal amplification. LME49870 combined with very low voltage-noise density (2.7nV/) √ ^Hz) with a very low THD + N (0.00003%), easily meeting the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, LME49870 boasts a high slew rate of ±20V/μs and an output current capability of ±26 milliamps. 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.
LME49870's excellent CMRR (120 dB), (PSRR120 dB) and V OS (0.1mV) amplifiers provide excellent operational amplifier DC performance.
LME49870 has a wide supply voltage range ± 2.5V to ± 22V. LME49870 maintain excellent common-mode rejection ratio, supply rejection, and low input bias current over this supply voltage range. LME49870 is stable unit gain. This op-amp achieves excellent AC performance with high values of up to 100pF for complex loads while driving.
LME49870 is an 8-pin narrow-body SOIC. Each package presentation board.
