Description

The LM833 is a monolithic dual operational

amplifier particularly well-suited to audio

applications.

It offers low voltage noise (4.5 nV/√Hz) and high

frequency performances (15 MHz gain bandwidth

product, 7 V/µs slew rate).

In addition, the LM833 has a very low distortion

(0.002%) and excellent phase/gain margins.
