The LM4681 is a fully integrated single supply, CLASS D audio power amplifier solution.

a stereo headphone amplifier that delivers 80mW into a 32Ω headset with less than 0.5% THD. The LM4681’s I2C/SPI (selectable) volume control has a +30dB to.
48dB range when speakers are driven and a range of +13dB to.
65dB when headphones are connected. All amplifiers are protected by thermal shutdown. Additionally, the high efficiency power amplifiers have output current limit. With a 8Ω load, the IC’s efficiency for a 6W power level is 85%. The IC features click and pop reducti.
