Dual JFET Input Audio Operational Amplifier
General Description
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 significant-
ly. It combines low voltage noise density (7nV/
low THD+N (0.00003%). The LME49880 has a high slew rate
of ±17 V/μs and an output current capability of ±22 mA. It
drives 600Ω loads to within 1.3V of either power supply volt-
age.
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 perfor-
mance. The LME49880 is unity gain stable and capable of
driving complex loads with values as high as 100pF. It is
available in an 8-lead narrow body PSOP.
