The LM833DR is a dual high-speed audio Operational Amplifier with high-performance specifications for use in data-signal applications. Dual amplifier is 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.
