Only Three External Components
The TPA2005D1 is a 1.4-W high efficiency filter-free
class-D audio power amplifier in a MicroStar Junior
–
Optimized PWM Output Stage Eliminates
BGA, QFN, or MSOP package that requires only
LC Output Filter
three external components.

–
Improved PSRR (-71 dB at 217 Hz) and
cellular handsets. A fast start-up time of 9 ms with
Wide Supply Voltage (2.5 V to 5.5 V)
minimal pop makes the TPA2005D1 ideal for PDA
Eliminates Need for a Voltage Regulator
applications.
–
Fully Differential Design Reduces RF
In cellular handsets, the earpiece, speaker phone,
Rectification and Eliminates Bypass
and melody ringer can each be driven by the
Capacitor
TPA2005D1. The device allows independent gain
control by summing the signals from each function
–
Improved CMRR Eliminates Two Input
