I bought 4 of these brand new old stock LME49990 opamps from a reputable seller on DIYAudio. I planned to solder them onto SOIC-DIP adapters for my famous Audiokarma-sourced CNC Phono stage but got out of vinyl hobby altogether. Price is $50 shipped in cont. USA.


These amps are very hard to source these days.

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.
