Class-G headphone amplifiers from Texas Instruments
Users of music phones and MP3 players can benefit from dramatically extended music playback time enabled by two new 25-mW Class-G, DirectPath stereo headphone amplifiers from Texas Instruments, which adjust their voltage supplies to the audio signal to minimize power dissipation. In a standalone Lithium-Ion battery test between TI’s Class-G technology and a competing ground-referenced Class-AB device, the TPA6140A2 and TPA6141A2 reduced pow...
