DESCRIPTION
The LM4917 is a stereo, output capacitor-less headphone amplifier capable of delivering 95m W of continuous average power into a 16Ω load with less than 1% THD+N from a single 3V power supply.
The LM4917 provides high quality audio reproduction with minimal external ponents. A ground referenced output eliminates the output coupling capacitors typically required by single-ended loads,...
