TPA6139A2 Description
The TPA6139A2 is a 25-mW, pop-free stereo headphone driver designed to reduce ponent count, board space and cost. It is ideal for singlesupply electronics where size and cost are critical design parameters. The TPA6139A2 device does not require a power supply greater than 3.3 V to generate its 25 mW, nor does it require a split rail power supply.
