3 Description
The LM833 device is a dual operational amplifier with
high-performance specifications for use in quality
audio and data-signal applications. Dual amplifiers
are utilized widely in audio circuits optimized for all
preamp and high level stages in PCM and HiFi
systems. The LM833 device is pin-for-pin compatible
with industry-standard dual operation amplifiers. With
addition of a preamplifier, the gain of the power stage
can be greatly reduced to improve performance.
