TPA6141A2 25mW G 类 DirectPath™ 立体声耳机放大器 (TPA6141)
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. DirectPathTM technology eliminates external DC-blocking capacitors.
The device features fully differential inputs with an integrated low pass filter to reduce system noise pickup between the audio source and the headphone amplifier and to reduce DAC out-of-band noise. The high power supply noise rejection performance and differential architecture provides increased RF noise immunity
