LM833 双路高速音频运算放大器

The LM833 is a dual operational amplifier with high-performance specifications for use in quality audio and data-signal applications. This device operates over a wide range of single- and dual-supply voltage with low noise, high-gain bandwidth, and high slew rate. Additional features include low total harmonic distortion, excellent phase and gain margins, large output voltage swing with no deadband crossover distortions, and symmetrical sink/source performance.

The dual amplifiers are utilized widely in circuit of audio optimized for all preamp and high level stages in PCM and HiFi systems. LM833 is pin-for-pin compatible with industry-standard dual operation amplifiers’ pin assignments. With addition of a preamplifier, the gain of the power stage can be greatly reduced to improve performance
