The LM4982 is a ground referenced, variable gain audio power amplifier capable of delivering 80mW of continuous average power into a 16 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 pump technology to generate the LM4982's negative supply voltage. This eliminates the need for output-coupling capacitors typically used with single-ended loads.
