TPA6140A2 具有 I2C 音量控制的 25mW G 类 DirectPath™ 立体声耳机放大器 (TPA6140)
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. DirectPath™ 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 µW per channel into 32 . Shutdown mode reduces the supply current to less than 3 µA and is activated through the I2C interface.
