TPA6141A2 Overview
The TPA6141A2 (also known as TPA6141) is a Class-G DirectPath™ stereo headphone amplifier with selectable gain. Class-G technology maximizes battery life by adjusting the voltage supplies of the headphone amplifier based on the audio signal level. At low level audio signals, the internal supply voltage is reduced to minimize power dissipation.
