LME49990 is part of an ultra-low distortion, low noise, high slew rate operational amplifier series, high performance, high fidelity applications, fully optimized and specified. LME49990 combined with low voltage noise density (0.9nV/) √ ^ Hz) with a low THD + N (0.00001%). LME49990 has a high slew rate of ±22V/μs and an output current ± 27 milliamps capability. Drive any supply voltage of 2V over a load range of 600Ω.
LME49990 excellent gain (135 dB), CMRR (137 dB), (PSRR144 dB), and V OS (130 μV) amplifiers for excellent operational amplifier DC performance. LME49990 has a wide ± 5V ± 18V supply voltage range. LME49990 is unity-gain stable and offers 8-pin narrow-body SOIC and LLP.
