TEL: 18617042732 ***: 3073924495 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 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 (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 applicati***.
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.
