LME49880 双路 JFET 输入音频运算放大器

The LME49880 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity application. The LME49880 is developed in JFET technology and reducing the flicker noise as well as the noise corner frequency significantly. It combines low voltage noise density (7nV/ √ ^Hz) with very low THD+N (0.00003%). The LME49880 has a high slew rate of ±17 V/μs and an output current capability of ±22mA. It drives 600Ω loads to within 1.3V of either power supply voltage.

The LME49880 has a wide supply range of ±5V to ±17V. Its outstanding GAIN (120dB), and low input bias current (5pA) give the amplifier excellent operational amplifier DC performance
