TPA6047A4

The TPA6047A4 is a stereo audio power amplifier and DirectPath headphone amplifier in a thermally anhanced, space-saving, 32-pin QFN package. The speaker amplifier is capable of driving 2.1 W per channel continuously into 4-Ω loads at 5 v. The headphone amplifier achieves a minimum of 100mW at 10% THD+N from a 5-V supply. A built-in internal 4-step gain control for the speaker amplifier and a fixed -1.5 V/V gain for ther headphone amplifier minimizes external components needed. Independent shutdown control and dedicated inpunts for te speaker and headphone allow the TPA6047A4 to simultaneously drive both headphones and internal speakers. Differential inputs to the speaker amplifiers offer superior power-supply and common-mode noise rejection.
