DESCRIPTION
The TPA2010D1 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.
Features like 88% efficiency, −75-dB PSRR, improved
RF-rectification immunity, and 8 mm² total PCB area make
the TPA2010D1 ideal for cellular handsets. A fast start-up
time of 1 ms with minimal pop makes the TP2010D1 ideal
for PDA applications.
In cellular handsets, the earpiece, speaker phone, and
melody ringer can each be driven by the TPA2010D1. The
TPA2010D1 allows independent gain while summing
signals from seperate sources, and has a low 36 µV noise
floor, A-weighted.
