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

mVRMS noise floor, A-weighted.
