The LME49990 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. The LME49990 combines low voltage noise density (0.9nV/√Hz) with vanishing low THD+N (0.00001%). The LME49990 has a high slew rate of ±22V/μs and an output current capability of ±27mA. It drives 600Ω loads to within 2V of either power supply voltage.
The LME49990’s outstanding Gain (135dB), CMRR (137dB), PSRR (144dB), and VOS (130μV) give the amplifier excellent operational amplifier DC performance. The LME49990 has a wide supply range of ±5V to ±18V. The LME49990 is unity gain stable and is available in an 8-lead narrow body SOIC and VQFN.
