📥 Download Datasheet

General Description

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.
