LME49743 is a low-distortion, low-noise, high-slew rate op-amp optimized and high-performance, high-fidelity application is fully specified. LME49743 op-amp provides excellent audio performance and superior audio signal amplification. LME49743 combined with low voltage noise density (3.5nV/) √ ^Hz) and THD+N (0.0001%) to easily meet demanding audio applications. To ensure that the most challenging loads are uncompromising drives, LME49743 ± 12V/μs slew rate and output current ± 21 milliamps capability.

LME49743 excellent CMRR (106 dB), (PSRR98 dB) and V OS (± 0.15mV) give the amplifier excellent operational amplifier DC performance.

LME49743 has a wide supply voltage range ± 4.0V to ± 17V. LME49743 input circuitry maintains excellent common mode, supply rejection, and low input bias current over this supply voltage range. LME49743 is stable unit gain.

LME49743 is a 14-pin TSSOP.
