The TPA2005D1 is a 1.4-W high-efficiency filter-free
Resistor
class-D audio power amplifier in a MicroStar Junior
BGA, QFN, or MSOP package that requires only
Improved PSRR (–71 dB at 217 Hz) and
three external components.
Wide Supply Voltage (2.5 V to 5.5 V)
Eliminates Need for a Voltage Regulator
Features like 84% efficiency, –71-dB PSRR at
217 Hz, improved RF-rectification immunity, and
Fully Differential Design Reduces RF
15-mm2 total PCB area make the TPA2005D1 ideal
Rectification and Eliminates Bypass
for cellular handsets. A fast start-up time of 9 ms with
Capacitor
minimal pop makes the TPA2005D1 ideal for PDA
Improved CMRR Eliminates Two Input
applications.
Coupling Capacitors
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,
while minimizing noise to only 48
V
RMS.
