1.4 W into 8 Ω from 5.0 V (10% THD + N)  
1.25 W into 8 Ω from 5.0 V (1% THD + N)  
The TPA2054D4A features a stereo Class-D power  
amplifier along with a stereo DirectPath™ headphone  
amplifier. The TPA2054D4A has a mono differential  
input and two stereo single-ended (SE) inputs that  
can be configured as one stereo differential input.  
Both input channels have a 32-step volume control  
and the DirectPath headphone amplifier has a 4-level  
gain control for coarse volume adjustment. All  
amplifiers have output short-circuit and thermal-  
overload protection.

Input  
The Class-D amplifiers deliver 1.25 W into 8 Ω at 1%  
THD from a 5.0 V supply, and 700 mW from 3.6 V.  
The DirectPath headphone amplifier features an  
output voltage limiter to reduce the maximum output  
power to one of seven possible limits. The voltage  
limiter is programmed through the I2C interface.

•
3:1 Input MUX with Mode Control  
32-Step Volume Control for Both Input  
Channels  
•
Independent Shutdown for Headphone and  
Class-D Amplifiers  
DirectPath eliminates the need for external DC-  
blocking output capacitors to the headphones. The  
built-in charge pump creates a negative supply  
voltage for the headphone amplifier, allowing a 0 V  
DC bias at the output.  
•
•
Short-Circuit and Thermal-Overload Protection  
±8 kV HBM ESD Protection on Headphone  
Outputs  
I2C™ Interface  
•
•
The DirectPath headphone amplifier gains are +6 dB  
(default), 0 dB, –6 dB, and –14 dB, selected through  
the I2C interface. This allows the headphone volume  
to be different from the loudspeaker volume if both  
are used simultaneously.

The TPA2054D4A has a 3:1 input MUX for audio  
source selection. Mode and gain controls operate  
from a 1.7 V to 3.6 V compatible I2C interface.  
The voltage supply range for both the Class-D  
amplifiers and the headphone charge pump is 2.5 V  
to 5.5 V. The Class-D amplifiers use a combined  
7 mA and the headphone amplifier uses 10 mA of  
typical quiescent current.
