FEATURES  
DESCRIPTION  
The TPA2029D1 is a mono, filter-free Class-D audio  
power amplifier with dynamic range compression  
(DRC) and automatic gain control (AGC). It is  
available in a 1.63 mm x 1.63 mm WCSP package.

Filter-Free Class-D Architecture  
3 W Into 4 Ω at 5 V (10% THD+N)  
880 mW Into 8 Ω at 3.6 V (10% THD+N)  
Power Supply Range: 2.5 V to 5.5 V  
3 Selectable AGC functions  
Low Supply Current: 1.8 mA  
Low Shutdown Current: 0.2 μA  
High PSRR: 80 dB  
The DRC/AGC function in the TPA2029D1 can be  
enabled and disabled. The DRC/AGC function is  
configured to automatically prevent distortion of the  
audio signal and enhance quiet passages that are  
normally not heard. The DRC/AGC is also configured  
to protect the speaker from damage at high power  
levels and compress the dynamic range of music to fit  
within the dynamic range of the speaker. The  
TPA2029D1 is capable of driving 3 W at 5 V into 4Ω  
load or 880 mW at 3.6 V into 8Ω load. The device  
features an enable pin and also provides thermal and  
short circuit protection.  
Fast Start-up Time: 5 ms  
AGC Enable/Disable Function  
Limiter Enable/Disable Function  
Short-Circuit and Thermal Protection  
Space-Saving Package  
In addition to these features, a fast start-up time and  
small package size make the TPA2029D1 an ideal  
choice for Notebook PCs, PDAs and other portable  
applications.
