TI Class-G Technology Significantly Prolongs  
Battery Life and Music Playback Time  
The TPA6141A2 (also known as TPA6141) is a  
Class-G DirectPath™ stereo headphone amplifier  
with selectable gain. Class-G technology maximizes  
battery life by adjusting the voltage supplies of the  
headphone amplifier based on the audio signal level.  
At low level audio signals, the internal supply voltage  
is reduced to minimize power dissipation.

Outputs Biased at 0 V  
The device features fully differential inputs with an  
integrated low pass filter to reduce system noise  
pickup between the audio source and the headphone  
amplifier and to reduce DAC out–of–band noise. The  
high power supply noise rejection performance and  
differential architecture provides increased RF noise  
immunity. For single–ended input signals, connect  
INL+ and INR+ to ground.

SGND Pin Eliminates Ground Loop Noise  
Wide Power Supply Range: 2.5 V to 5.5 V  
100 dB Power Supply Noise Rejection  
Built-in Input Low Pass Filter  
The device operates from a 2.5 V to 5.5 V supply  
voltage. Class-G operation keeps total supply current  
below 5.0 mA while delivering 500 μW per channel  
into 32 Ω. Shutdown mode reduces the supply  
current to less than 3 μA and is activated through the  
EN pin.  
Gain Settings: 0 dB and 6dB  
Short-Circuit Current Limiter  
Thermal-Overload Protection  
The device has built-in pop suppression circuitry to  
completely eliminate disturbing pop noise during  
turn-on and turn-off. The amplifier outputs have  
short-circuit and thermal-overload protection along  
with ±8 kV HBM ESD protection, simplifying end  
equipment compliance to the IEC 61000-4-2 ESD  
standard.
