The TPA2010D1 (sometimes referred to as TPA2010) 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 die-size ball grid array (DSBGA) 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 (TPA2010) class-D amp ideal for cellular handsets. A fast start-up time of 1 ms with minimal pop makes the TPA2010D1 (TPA2010) 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 separate sources and has a low 36 µV noise floor that is A-weighted.
