description  
The TPA032D01 is a monolithic power IC mono  
audio amplifier that operates in extremely efficient  
Class-Doperation, usingthehighswitchingspeed  
of power DMOS transistors to replicate the analog  
input signal through high-frequency switching of  
the output stage. This allows the TPA032D01 to  
beconfiguredasabridge-tiedload(BTL)amplifier  
capable of delivering up to 10 W of continuous  
average power into a 4-Ω load at 0.5% THD+N  
from a 12-V power supply in the high-fidelity audio  
frequency range (20 Hz to 20 kHz). A BTL  
configuration eliminates the need for external  
coupling capacitors on the output. A chip-level  
shutdown control is provided to limit total supply  
current to 20 µA, making the device ideal for  
battery-powered applications.

The output stage is compatible with a range of power supplies from 8 V to 14 V. Protection circuitry is included  
to increase device reliability: thermal and under-voltage shutdown, with a status feedback terminal for use when  
any error condition is encountered.  
The high switching frequency of the TPA032D01 allows the output filter to consist of three small capacitors and  
two small inductors per channel. The high switching frequency also allows for good THD+N performance.  
The TPA032D01 is offered in the thermally enhanced 48-pin PowerPAD TSSOP surface-mount package  
(designator DCA).
