Explore power amplifier integrated circuit from National Semiconductor LM4780. What's so special? Well, first of all - a very low harmonic distortion. In general, manufacturers indicate the maximum power of his ingenious craft regularly with the harmonic content of 10%. At the same chip, CT in the specified maximum power is only 0.5%! Therefore, it is the most honest of all mikruha've found.

The chip implements two identical amplifier channels and features are given for the stereo amplifier. Circuit can also operate in mono - the inclusion of the bridge. In this case, the power output at CT = 0.5% of 120 watts. Other features remain virtually unchanged.
