Audio Amp Headphone/Speaker 2-CH Stereo 2.6W Class-AB 32-Pin VQFN EP T/R, TPA6045A4CRHBR, Texas Instruments

The TPA6045A4C is a stereo audio power amplifier and DirectPath headphone amplifier in a thermally enhanced, space-saving, 32-pin QFN package. The speaker amplifier is capable of driving 2.1 W per channel continuously into 4-O; loads at 5 V.The headphone amplifier achieves a minimum of 85 mW at 1% 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 the headphone amplifier minimizes external components needed.Independent shutdown control and dedicated inputs for the speaker and headphone allow the TPA6045A4C to simultaneously drive both headphones and internal speakers.Differential inputs to the speaker amplifiers offer superior power-supply and common-mode noise rejection.
