Description

General part information

TPA2005 Series

The TPA2005D1 is a 1.4-W high efficiency filter-free class-D audio power amplifier in a MicroStar Junior™ BGA, QFN, or MSOP package that requires only three external components.

Features like 84% efficiency, –71-dB PSRRat 217 Hz, improved RF-rectification immunity, and15 mm2total PCB area make the TPA2005D1 ideal for cellular handsets. A fast start-up time of 9 ms with minimal pop makes the TPA2005D1 ideal for PDA applications.

In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the TPA2005D1. The device allows independent gain control by summing the signals from each function while minimizing noise to only 48 μVRMS.
