DESCRIPTION
The TPA2036D1 is a 2.5-W high efficiency filter-free
class-D audio power amplifier (class-D amp) in a 1,45
mm × 1,45 mm wafer chip scale package (WCSP)
that requires only three external components.
Features such as 88% efficiency, –75-dB PSRR,
improved RF immunity, and 8 mm² total PCB area
make TPA2036D1 ideal for cellular handsets. A fast
start-up time of 1 ms with minimal pop makes
TPA2036D1 ideal for portable applications.
In cellular handsets, TPA2036D1 is capable of driving
the earpiece, speaker phone, and melody ringer.
TPA2036D1 allows independent gain while summing
signals from separate sources, and has a low 36
µV_RMS noise floor, A-weighted.
