The LME49743 is a low distortion, low noise, high slew rate operational amplifier optimized and fully specified for high performance, high fidelity applications. The LME49743 audio operational amplifier delivers superior audio signal amplification for outstanding audio performance. The LME49743 combines low voltage noise density (3.5nV/√Hz) and THD+N (0.0001%) to easily satisfy demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49743 has a slew rate of ±12V/μs and an output current capability of ±21mA.
The LME49743's outstanding CMRR(106dB), PSRR(98dB), and VOS (±0.15mV) give the amplifier excellent operational amplifier DC performance.
The LME49743 has a wide supply range of ±4.0V to ±17V. Over this supply range the LME49743’s input circuitry maintains excellent common-mode, power supply rejection, and low input bias current. The LME49743 is unity gain stable.
The LME49743 is available in 14–lead TSSOP.
