LM4982 Stereo Headphone Amplifier

The LM4982 is a ground referenced, variable gain audio power amplifier capable of delivering 80mW of continuous average power into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply. The I2C volume control allows +18 to -76 dB gain settings. The LM4982 utilizes advanced charge pu.
