DESCRIPTION  
Maximum Battery Life and Minimum Heat  
The TPA2031D1 is a 2.5-W high efficiency filter-free  
class-D audio power amplifier in a 1,45 mm × 1,45  
mm wafer chip scale package (WCSP) that requires  
only three external components.  
Efficiency With an 8-Speaker:  
88% at 400 mW  
2.8-mA Quiescent Current  
0.5-µA Shutdown Current  
Features like 88% efficiency, –75-dB PSRR,  
improved RF-rectification immunity, and 8 mm2 total  
PCB area make the TPA2031D1 class-D amp ideal  
for cellular handsets. 32 ms start-up time allows the  
Only Three External Components  
Optimized PWM Output Stage Eliminates

GPIO  
Improved PSRR (–75 dB) and Wide Supply  
Voltage (2.5 V to 5.5 V) Eliminates Need for  
a Voltage Regulator  
enable/shutdown control as the CODEC without  
passing through the CODEC turn-on pop.  
In cellular handsets, the earpiece, speaker phone,  
and melody ringer can each be driven by the  
TPA2031D1. The TPA2031D1 allows independent  
gain while summing signals from separate sources,  
and has a low 36 µV noise floor, A-weighted.
