FEATURES  
Qualified for Automotive Applications  
Space-Saving Packages  
1.4 W Into 8 From a 5-V Supply at  
THD = 10% (Typ)  
3 mm x 3 mm QFN package (DRB)  
3 mm x 5 mm MSOP PowerPAD™ Package  
(DGN)  
Maximum Battery Life and Minimum Heat  
Efficiency With an 8-Speaker:  
DESCRIPTION  
84% at 400 mW  
79% at 100 mW  
The TPA2005D1 is a 1.4-W high-efficiency filter-free  
class-D audio power amplifier in a QFN or MSOP  
package that requires only three external  
components.  
2.8-mA Quiescent Current  
0.5-mA Shutdown Current  
Only Three External Components  
Features like 84% efficiency, –71-dB PSRR at  
217 Hz, improved RF-rectification immunity, and  
15-mm2 total PCB area make the TPA2005D1 ideal  
for cellular handsets. A fast start-up time of 9 ms with  
minimal pop makes the TPA2005D1 ideal for PDA  
applications.  
Optimized PWM Output Stage Eliminates  
LC Output Filter  
Internally Generated 250-kHz Switching  
Frequency Eliminates Capacitor and  
Resistor  
In cellular handsets, the earpiece, speaker phone,  
and melody ringer can each be driven by the  
TPA2005D1. The device allows independent gain  
control by summing the signals from each function,  
Improved PSRR (–71 dB at 217 Hz) and  
Wide Supply Voltage (2.5 V to 5.5 V)  
Eliminates Need for a Voltage Regulator  
Fully Differential Design Reduces RF  
Rectification and Eliminates Bypass  
Capacitor  
while minimizing noise to only 48 mVRMS
