LME49723 is a high-performance, high-fidelity application of the ultra-low distortion, low noise, high slew rate op amp series, fully optimized and specified parts. Combined with the country's most advanced circuit design and advanced cutting-edge process technology, LME49723 audio op-amplifier provides excellent audio performance and superior audio signal amplification. LME49723 combined with very low voltage and noise density (3.6nV/ √ ^Hz) with a very low THD + N (0.0002%), easily meeting the most demanding audio applications. To ensure that the most challenging loads are uncompromising drives, LME49723 ± 20V/μs slew rate and output current ± 26 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.
LME49723 excellent CMRR (100 dB), (PSRR100 dB) and V OS (0.3mV) allow the amplifier to operate the DC performance of the amplifier.
LME49723 has a wide supply voltage range ± 2.5V to ± 17V. LME49723 input circuitry maintains excellent common-mode and supply rejection over this supply voltage range, as well as maintaining its low input bias current. LME49723 is stable unit gain.
LME49723 is in an 8-pin narrow-body SOIC. Demo boards are provided for each package.
