LME49860 chip's ultra-low distortion, low noise, high slew rate operational amplifier series, high performance, high fidelity applications, fully optimized and specified parts. Combined with the country's most advanced circuit design and advanced cutting-edge process technology, the audio op-amplifier of LME49860 chip can provide excellent audio performance and superior audio signal amplification. LME49860 chip 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 uncompromising drives, LME49860 chip has a high slew rate of ±20V/μs and an output current capability of ±26 mA. 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.
LME49860 chip's excellent CMRR (120 dB), (PSRR120 dB) and V OS (0.1mV) amplifiers provide excellent op amp DC performance.
LME49860 chip has a wide supply voltage range of ± 2.5V to ± 22V. LME49860 chip maintains excellent common-mode rejection ratio, supply rejection, and low input bias current over this supply voltage range. LME49860 chip is unit gain stable. This op-amp achieves excellent AC performance with high values of up to 100pF for complex loads while driving.
LME49860 chip is an 8-pin narrow-body SOIC and an 8-pin plastic DIP package. Each package presentation board.
