General Description

The TPA6140A2 (also known as TPA6140) is a Class-G DirectPath™ stereo headphone amplifier with built-in I2C volume control.

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.
