Description
General part information
TPA6139A2 Series
The TPA6139A2 is a 25-mW, pop-free stereo headphone driver designed to reduce component count, board space and cost. It is ideal for single-supply 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.
The TPA6139A2 device was designed using TI’s patented DirectPath™ technology, which integrates a charge pump to generate a negative supply rail that provides a clean, pop-free ground biased output. The TPA6139A2 is capable of driving 25 mW into a 32-Ω load and 2 Vrms into a 600-Ω load. DirectPath also allows the removal of the costly output DC-blocking capacitors.
