Description for the TPA6139A2

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.

The device has fixed gain single-ended inputs with a gain select pin. Using a single resistor on this pin, the designer can choose from 13 internal programmable gain settings to match the line driver with the CODEC output level. It also reduces the component count and board space.

Headphone outputs have &plusm;8-kV HBM ESD protection enabling a simple ESD protection circuit. The TPA6139A2 has built-in active mute control with more that 80-dB attenuation for pop-free mute ON and OFF control.

The TPA6139A2 device is available in a 14-pin TSSOP and a 16-pin QFN. For a pin-compatible, 2-Vrms line driver see DRV612.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
