LM4830 Two-Way Audio Amplification

The LM4830 is an integrated solution for two-way audio amplification. It contains a bridge-connected audio power amplifier capable of delivering 1W of continuous average power to an 8Ω load with less than 1% THD from a 5V power supply. It also has the capability of driving 100 mW into a single-ended.
