FEATURES
DESCRIPTION
The TPA6139A2PW is a 25mW Pop-Free stereo
23
DirectPath
Head Phone driver designed to reduce component
– Eliminates Pop/Clicks
count, board space and cost. It is ideal for single
– Eliminates Output DC-Blocking Capacitors
supply electronics where size and cost are critical
design parameters.
– 3 V to 3.6 V Supply voltage
Low Noise and THD
The TPA6139A2 does not require a power supply
greater than 3.3V to generate its 25mW, nor does it
– SNR > 105 dB at –1x Gain
require a split rail power supply.
– Typical Vn < 15 μVms 20-20kHz at –1x Gain

DIRECTPATH
– THD+N < 0.003% at 10kΩ Load and –1x
technology which integrates a charge pump to

pop-free ground biased output. The TPA6139A2 is
capable of driving 25mW into 32

the costly output DC-blocking capacitors.
Programmable Gain Select Reduces
The device has fixed gain single ended inputs with a

designer can choose from 13 internal programmable
Active Mute With More Than 80dB Attenuation
gain settings to match the line driver with the Codec
output level. It also reduces the component count and
