Product Summary
The TPA6040A4RHBR 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 W per channel continuously into 4-W 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. The applications of the TPA6040A4RHBR include Notebook Computers, Portable DVD.
