The TPA6140A2 (also known as TPA6140) is a Class-G DirectPathTM 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. DirectPathTM technology eliminates external DC-blocking capacitors. The device operates from a 2.5 V to 5.5 V supply voltage. Class-G operation keeps total supply current below 5.0 mA while delivering 500 W per channel into 32 . Shutdown mode reduces the supply current to less than 3 A and is activated through the I2C interface. |
