DESCRIPTION  
The TPA2005D1 is a 1.4-W high-efficiency filter-free  
class-D audio power amplifier in a MicroStar Junior™  
BGA, QFN, or MSOP package that requires only  
three external components.  
– Optimized PWM Output Stage Eliminates LC  
Output Filter  
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.  
– Internally Generated 250-kHz Switching  
Frequency Eliminates Capacitor and  
Resistor  
– Improved PSRR (-71 dB at 217 Hz) and  
Wide Supply Voltage (2.5 V to 5.5 V)  
Eliminates Need for a Voltage Regulator  
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,  
– Fully Differential Design Reduces RF  
Rectification and Eliminates Bypass  
Capacitor  
while minimizing noise to only 48 µVRMS  
.
– Improved CMRR Eliminates Two Input  
Coupling Capacitors
